Christophe Galtier insisted Kylian Mbappe is happy at Paris Saint-Germain, though admitted Lionel Messi's future with the French giants is undecided.

Mbappe is the leading marksman in Ligue 1 this season with 12 goals – one ahead of team-mate Neymar – while Messi tops the assists chart with 10, having also found the net seven times.

The France international was heavily linked with a free transfer to Real Madrid last season, but eventually signed a new three-year deal with the reigning Ligue 1 champions in May.

Many believed financial gain played a significant factor in Mbappe's decision, while reports have also suggested the 23-year-old has recently been reconsidering whether he wants to remain at the club.

But Galtier told Marca: "I don't think it was the money, because world-class players – whether in Spain, England or France – win it. They are not for the money. I think Kylian just loves PSG. 

"If he's happy, why shouldn't Kylian be here next season? From the moment the player enjoys on the field and feels that he is in a team that can win and that can conquer great challenges, he has no reason to leave."

Asked if he felt Mbappe was happy at PSG, Galtier added: "Yes, sure. Guaranteed."

Meanwhile, Messi's existing contract is due to expire next June, although there is the option of extending his stay in the French capital for an additional year.

"There are many parameters," Galtier said when asked what it would take for the Argentina captain to remain at the club beyond this season. 

"The first thing is their desire. Do you want to continue at PSG? Are you happy here? The first thing to know is if he wants to continue. All these types of decisions are made between the player and [football advisor] Luis Campos."

Denmark coach Kasper Hjulmand is not frightened by Kylian Mbappe but conceded there is only so much you can do to stop the France striker.

Mbappe scored in Les Bleus' 4-1 win against Australia in their World Cup Group D opener on Tuesday and looked razor sharp alongside Olivier Giroud.

Hjulmand's men ground out a goalless draw against Tunisia, although keeping another clean sheet against the defending champions may be trickier to achieve.

Asked if he was frightened at the thought of trying to keep Mbappe quiet, Hjulmand replied: "I don't think it's good to be frightened. We have plans to stop him. At Parken [in September] we had a good plan, a good structure. He had two or three chances and no matter what plans you have against top players, you can't keep them down.

"We have carried out plenty of analysis to try to minimise his impact, we don't want him to show the talent he has."

Hjulmand is hoping some insider knowledge will also help stifle France's threat with captain Simon Kjaer a team-mate of Giroud at Milan.

He added: "I hope it's an advantage. A player like Giroud is very good at what he does. It's a pleasure seeing so many strikers in the latter stages of their careers showing how to move in the box, showing how to be dangerous in their positioning and showing how to finish in the box.

"Giroud is better now than he was before, he is very dangerous. Simon knows him very well and we have been talking about the small details."

Denmark enjoyed back-to-back wins against Didier Deschamps' side in the Nations League earlier this year but Hjulmand knows facing them at a World Cup is a different proposition.

"We have tested them a couple of times but this is a different tournament," he said. "But we know that if we play our best we have a chance of getting a good result.

"To be able to do that, we have to take a big step forward in quality from the first match."

Denmark and France kick off six hours after the other Group D encounter between Australia and Tunisia, and Hjulmand admitted the result of that game could affect his approach to the game.

"I won't watch that game, but I will obviously know the outcome as it will influence how we approach our game," he said.

"I am only really talking about the last 25 minutes. We are focused on winning the match but the other game will influence our approach."

Dani Alves believes Kylian Mbappe "has still not understood" the value of playing with "geniuses" Lionel Messi and Neymar in Paris Saint-Germain's attack.

Mbappe is the leading marksman in Ligue 1 this season with 12 goals – one more than Brazil international Neymar – while he is just 11 away from breaking Edinson Cavani's club record tally of 200.

However, the France international has only registered two assists in the French top flight this term, with Messi (10) and Neymar (nine) recording 19 between them.

Alves spent two years playing alongside Mbappe and Neymar in Paris, having also previously won multiple honours alongside the latter and Messi at Barcelona.

The Brazil full-back who, at 39, was handed a chance to become his nation's oldest World Cup player, feels the 23-year-old Mbappe's goalscoring exploits would be even greater should be pass to his team-mates more often.

"Neymar and Messi are unique, they see and do things that no one else sees or can do," Alves told La Gazzetta dello Sport. "You have to be smart to take advantage of their potential, they are the two geniuses of football.

"I think I can touch the ball well, but when I was playing with Leo, I was giving him the ball. And if I play with Ney, I give him the ball. If Mbappe gave the ball to those two, he would score 150 goals [in a season].

"A great player always has to know and understand who he is playing with. Your team-mates enrich your qualities.

"Mbappe is a phenomenon who has still not understood that those who play in attack with him are more phenomenal than him."

Garang Kuol became Australia's youngest World Cup star on Tuesday but noted the "big difference" he must bridge in order to regularly rub shoulders with the likes of Kylian Mbappe.

Kuol, who at 18 years and 68 days old was the ninth-youngest player in the tournament's history, was brought on as a 73rd-minute substitute moments after the final goal in the Socceroos' 4-1 opening defeat to holders France.

The highly talented winger – already confirmed as a Newcastle United signing ahead of a January move – enjoyed a few bright touches yet saw a significant gap to his opponents.

Kuol did not start a single A-League game for Central Coast Mariners, although he scored six goals in 326 minutes from the bench.

Meanwhile, Mbappe was France's star man as they took the title in Russia 2018 four years ago and appears to be in the mood to repeat the feat.

"You could see the level that they're at," Kuol said afterwards.

"They're 6ft 4[in] people who are as quick as me, so there was a big difference between me and some of those players. Only hard work will get me to that level.

"I think it was a good taste to see the level the players are at. Some play in the Premier League, some play in the Champions League, so it was good to get that taste of the level."

Mbappe in particular was relentless after a slow start had seen Australia lead through Craig Goodwin in the ninth minute.

The Paris Saint-Germain forward scored the third goal before creating the fourth for Olivier Giroud, having also had a role in the second – again scored by Giroud.

Mbappe had 19 touches in the Australia box – the most by any player in a World Cup match since 1970 – and completed three dribbles.

Australia right-back Nathaniel Atkinson endured a torrid time, not helped by the introduction of attacking France left-back Theo Hernandez after his brother Lucas was injured attempting to prevent the Socceroos goal.

Atkinson was dribbled past twice and gave away possession on 12 occasions, including an error leading to France's second.

"It's obviously the first time I've come up against this type of opposition in my career," Atkinson said.

"Obviously, I've taken full responsibility for the second goal, but the beauty of the tournament is you can't dwell on it because you've got another game to fix it in three days.

"It's a good experience. It's an eye-opener. There's a reason [Mbappe] is earning 200million [Australian] dollars a year and I am where I am, but that's something to look forward to.

"It's good to come up against this calibre. You know what to work on. I know what to fix; I've played that scenario 50 times over and I could probably come up with 50 different solutions. That's football. I'm disappointed.

"It's just the physicality of the guy. The pace... it's not hidden how quick that guy is – you give him one step and he's gone.

"As a team, you can always come up with a plan, but sometimes if it's one-v-one and he gets the better of you, it's a learning curve.

"You can get your confidence up with getting a few challenges in, but there's a reason why he's one of the top three players in the world."

Australia are not giving up hope, inspired by Saudi Arabia's sensational defeat of Argentina earlier on Tuesday.

"Anything can happen," Atkinson added. "You see what Saudi did against Argentina.

"We've come up against the world champions, and there's a reason for that. They're a good footballing team. We can take confidence from the way we played early on in that game."

Didier Deschamps believes Kylian Mbappe is set for another memorable World Cup after he claimed a goal and an assist in France's 4-1 win over Australia, declaring: "It's his competition".

Mbappe became just the second teenager – after Pele in 1958 – to score in a World Cup final as France downed Croatia to win the tournament in Russia four years ago, and he made a strong start to this year's competition as Les Bleus claimed a comeback win.

Craig Goodwin handed Australia a surprise lead in Tuesday's Group D clash, but Mbappe built on first-half strikes from Adrien Rabiot and Olivier Giroud as France got off to a winning start.

At 23 years and 337 days old, Mbappe is now the youngest player to have scored five World Cup goals for France, and Deschamps expects him to go from strength to strength in Qatar. 

"Kylian has been one of the best players in the world for some time now, and he's feeling very confident," Deschamps said. "You can see that in the way he plays. He is calm and concentrated. 

"He has been in good form for quite some time. I knew he was going to be ready for this World Cup, it's his competition and he knows how to make the difference.

"He's always been able to play as part of a team, so that's great for us, and I've got a lot of attackers, but Kylian is, of course, an outstanding one."

France's victory ensured they became the first World Cup holders to make a winning start at the tournament since Brazil did so in 2006, while their current five-match winning run at the finals is their joint-longest such streak (also five across the 1986 and 1998 editions).

However, France's win was tarnished as they received yet another injury blow, with Bayern Munich's Lucas Hernandez limping out of the game in the aftermath of Australia's early goal.

Deschamps fears the defender may have sustained a serious injury, which could open the door for his brother Theo Hernandez to start Saturday's fixture against Denmark.

"With Lucas Hernandez, we're still waiting for the results of the tests, but I'm afraid it could be pretty serious," Deschamps said.

"It's true that Lucas' injury was a tough blow. I'll have to think about his replacement.

"You can't have three players for every position in your squad, but there is obviously Theo Hernandez and other alternatives."

Olivier Giroud equalled Thierry Henry's France goalscoring record as Les Bleus fought back to begin their World Cup defence with a 4-1 victory over Australia on Tuesday.

Having lost Karim Benzema, Paul Pogba and others to injury during a chaotic build-up to the tournament, France suffered another blow when Craig Goodwin fired Australia into an early lead.

But the holders responded well, with the impressive Adrien Rabiot recording a goal and an assist – the latter for Giroud – during a first-half turnaround.  

Kylian Mbappe then made the points safe with a fine glancing header before teeing up Giroud to nod home his landmark 51st goal as France took control of Group D.

Goodwin side-footed Mathew Leckie's cross into the roof of the net after nine minutes in a dream start for Australia but a quickfire France double turned the game around.

Rabiot contributed to both goals, nodding home Theo Hernandez's deep cross after 27 minutes before his cut-back allowed Giroud to tap in.

The end of an entertaining first half featured clear chances at both ends, with Mbappe firing over from close range before Jackson Irvine headed against the post.

Giroud went close to a spectacular second when he sent an acrobatic effort wide shortly after the break, while Antoine Griezmann saw a shot cleared off the goalline as France continued to press.

France finally had a deserved third goal after 68 minutes, with Mbappe diverting Ousmane Dembele's cross in off the post to clinch the win.

Mbappe sent in a fine cross for France's fourth just three minutes later, but the moment belonged to Giroud as he powered a header beyond Mathew Ryan to earn a slice of Les Bleus history.

What does it mean? Champions make strong start

France approached Tuesday's match looking to buck the recent trend of slow starts from World Cup holders – the reigning champions had only started with a win at three of the last 12 tournaments (D4 L5).

Given their chaotic preparations and Australia's early opener, Didier Deschamps may have been fearing the worst, but Les Bleus were ultimately good value for their win, which saw them take control of Group D following Denmark's draw with Tunisia.

Giroud matches Henry

Had Real Madrid's Ballon d'Or-winning forward Benzema been fit to feature against the Socceroos, Giroud would likely have been the player to miss out on a place in Deschamps' team.

However, Giroud – who played a key role in France's 2018 heroics in Russia – helped himself to a brace to draw level with Henry's tally of 51 goals for his country, hitting that number in eight fewer caps than the Arsenal great.

Rabiot takes centre stage

Injuries to Pogba and his 2018 World Cup-winning midfield partner N'Golo Kante opened the door for Rabiot to assume a central role in Qatar, and he did not let France down in their Group D opener.

Rabiot took the game by the scruff of the neck before the break, becoming the first France player to both score and assist a goal on his World Cup debut since Christophe Dugarry against South Africa in 1998

What's next?

France take on Denmark in their next Group D game on Saturday, while Australia face Tunisia on the same day.

France were many people's tip heading into Qatar 2022, having been so impressive when they lifted the World Cup four years ago.

On paper, they have the sort of team that would have most players of the FIFA 23 video game drooling, or at least, they did before injuries started to pile up.

Midfield pair Paul Pogba and N'Golo Kante, both so crucial to their 2018 success, had already been ruled out, and in the days since head coach Didier Deschamps announced his squad, two more high-profile names have been forced to withdraw.

The loss of Christopher Nkunku was a blow despite the RB Leipzig forward being unlikely to start, his 48 goal involvements (37 goals and 11 assists) in 2022 only second to France team-mate Kylian Mbappe (57 - 43 goals and 14 assists) among players from Europe's top five leagues.

Then there was Karim Benzema's withdrawal, a significant one considering the 2022 Ballon d'Or winner scored a spectacular 44 goals in 46 games for Real Madrid in 2021-22, helping the Spanish giants win LaLiga and the Champions League.

However, if any nation can handle a double blow like that, it is surely France.

When it comes to the team selection in their opening clash with Australia, Deschamps will likely turn to the same trio he used at Russia 2018, with Mbappe alongside one or both of Olivier Giroud and Antoine Griezmann.

Giroud has extra motivation, sitting just two behind Thierry Henry (51) as Les Bleus' all-time record goalscorer.

"Obviously I've got this target, this kind of bonus in my head to beat [Henry], but the main target as a team is to go as far as we can in the competition," the Milan striker said at a press conference on Friday.

France will need to improve on recent form though, having only won one of their six games in the UEFA Nations League in June and September (D2, L3).

Their first hurdle is an Australia team that only made it to Qatar by the skin of their teeth, needing a dramatic penalty shoot-out win against Peru in a play-off to advance.

Dancing substitute goalkeeper Andrew Redmayne was the hero that day, but head coach Graham Arnold will need inspiration from elsewhere if the Socceroos are to improve on their World Cup record.

They have been eliminated from the group stage in four of their five previous appearances, progressing only in 2006, when Arnold was assistant to Guus Hiddink.

Australia have won just 13 per cent of their matches at the World Cup (two of 16); only Bulgaria (12 per cent - three of 26) have a lower win rate among nations to play 10 or more games at the finals.

They have also suffered an injury blow of their own, with Martin Boyle pulling out after failing to recover from a knee problem. Melbourne City winger Marco Tilio has replaced him, and Arnold is backing the 21-year-old to step up.

"Marco has done everything that has been asked of him to be ready for this tournament," Arnold said. "He was an important member of our Tokyo 2020 Olympic team, he has started the A-League men's season well and he is familiar with the national team set-up and we are looking forward to what he can bring to our squad for the tournament."

PLAYERS TO WATCH

France - Kylian Mbappe

Losing players like Nkunku and Benzema is never a good thing, but the blow is softened when you can still turn to arguably the most electric attacker in world football.

Mbappe played a key role in France's World Cup success of 2018, scoring four goals in seven games in Russia. During the tournament, the young French star not only became his country's youngest ever goalscorer at a World Cup (19y 183d), but also, only the second teenager ever to score in a World Cup final after Brazilian icon Pele did so v Sweden in 1958.

He has also been near unstoppable for Paris Saint-Germain this season, with 19 goals in 20 games for the Ligue 1 giants.

Australia - Mat Ryan

Not just because Australia are likely to face a lot of shots against the world champions, but Ryan also brings experience that this side sorely need.

The former Valencia and Arsenal goalkeeper has not featured much for Copenhagen this season, with Kamil Grabara preferred, but he played all 11 of Australia's third and fourth-round matches in AFC qualifying for the World Cup.

Ryan is also set to appear in a third World Cup for Australia, the most of any goalkeeper for the nation. Should he feature in all three group games, he will move level with Mark Bresciano and Tim Cahill on nine World Cup appearances, the most for the Socceroos.

PREDICTION

Unsurprisingly, France are relatively overwhelming favourites to start with a win.

According to Stats Perform's AI model, Les Bleus have a 73.4 per cent chance of taking all three points, with Australia given just a 10.6 per cent chance.

The draw comes in at 16 per cent, which cannot be discounted given France's injuries and questionable form heading into Qatar.

Didier Deschamps has asked for "more understanding" as France adjust to their latest injuries, but Les Bleus intend to go "full steam ahead" with the same objectives as before.

France were already without Paul Pogba and N'Golo Kante for the World Cup and have now lost Christopher Nkunku and Karim Benzema on the eve of the tournament.

Deschamps' defending world champions head into their opener against Australia with uncertainty around much of their line-up, although the coach has "no worries at all" about Eduardo Camavinga's fitness and confirmed Raphael Varane is fit to start.

Asked on Monday if France would have to reconsider their approach to the finals, Deschamps disagreed, although he asked the assembled media for their support.

"It is full steam ahead with the team we have available to us," he said.

"Less ambition and less desire to do everything to get to the end? I don't think so. But if we could have more understanding from the media, if you could cut us a little more slack, that would be great.

"But we know what is asked of us. We are not counting our chickens before they are hatched, we know our three opponents ahead of us.

"We know Australia very well, but you haven't asked me anything about Australia. That's perfect."

Despite their difficulties, Deschamps says France have "no apprehension" and "no anxiety", even with the past three World Cup holders exiting in the first round.

"This is based on statistics, probability, facts, but I think each team has undergone their own journey to get where they are today," he said.

"It is up to us to have a squad that is aware of the objective of the first game. We're not going to think about what could have been.

"What is important is to focus on the first game against Australia. Everything before is on the sideline now.

"There is analysis that can be made, do with them what you will, but we will be ready for tomorrow."

In the absence of Benzema, Kylian Mbappe is set to have an even more prominent role, having starred in France's Russia 2018 success.

"[Mbappe] played an important role four years ago on the pitch," Deschamps said. "He was very mature at the time and is even more mature now because of what's gone on over the course of the past four years. There's been more global recognition, more responsibility.

"Obviously he has what it takes to stand out from the crowd, to score; his aura is second to none. This was the case four years ago, it still is the case now."

According to captain Hugo Lloris, Mbappe is "involved, relaxed, concentrated, focused".

Lloris was also asked about the OneLove captain's armband – a campaign that promotes "inclusion and sends a message against discrimination of any kind".

The France skipper had already confirmed he would not be wearing the armband, and it emerged shortly after his news conference other countries were backing out of the campaign following the threat of FIFA sanctions.

"FIFA is organising this competition," Lloris said. "It is therefore up to FIFA to put into place a regulatory framework.

"As players, we're here to play football and represent our teams to the best we can on a sporting front. I would prefer to stay in my box. I am a player and a competitor of this competition.

"Yes, there are many causes that are important and should be supported. They're commendable. But it's up to FIFA to take decisions with the organisation of the competition."

Kylian Mbappe penned a new Paris Saint-Germain deal in May, extending his contract until 2025.

That came after a prolonged courtship from Real Madrid for his services, while several other top clubs were interested.

But Mbappe has again been linked with a move away from the French capital, despite re-committing only months ago.

TOP STORY – MBAPPE WANTS PSG EXIT, MAN UTD CIRCLING

Kylian Mbappe is reportedly pushing for an exit from PSG during the January transfer window, claims Sport.

According to the report, Manchester United are preparing an audacious bid to land the 23-year-old France forward, with Liverpool and Real Madrid also in contention.

Mbappe wants PSG to let him go if a reasonable offer comes in during January, although United may not suit his football aspirations in the short term.

ROUND-UP

- Tottenham are keeping a close watch on Everton winger Anthony Gordon ahead of the January transfer window, reports Football London. Gordon, who also has interest from Chelsea, still has three years left on his Toffees deal.

- Chelsea's strategy with Romelu Lukaku is set to change, meaning he is unlikely to remain with Inter, claims Calciomercato. The Blues want to sell him for a major transfer fee at the end of this season, rather than loaning him back to Inter, as the Nerazzurri had hoped.

- Bild claims Borussia Dortmund have no plans to sell Raphael Guerreiro in January, amid interest from Leeds United and West Ham. Guerreiro is out of contract at the end of the season.

- Sevilla forward Youssef En-Nesyri looms as a January option for West Ham, according to Calciomercato.

Eduardo Camavinga backed Kylian Mbappe to deal with the added pressure after Karim Benzema was ruled out of the World Cup for France.

Didier Deschamps' side start their title defence in Qatar against Australia in Tuesday's Group D clash, but Les Bleus will do so without two key attacking figures.

Christopher Nkunku tore the lateral collateral ligament in his left knee after Tuesday's collision with Camavinga in training, before a thigh issue on Saturday for Benzema ruled the talisman out of the tournament.

France, who were already without Paul Pogba and N'Golo Kante, still have a plethora of attacking options with Mbappe, Antoine Griezmann, Olivier Giroud and Ousmane Dembele the likely starting contenders.

Real Madrid midfielder Camavinga believes Mbappe will step up in the absence of Benzema, given the 23-year-old is already used to dealing with pressure for both France and Paris Saint-Germain.

"Kylian can do it. He is used to having everything on his back. He's used to receiving this pressure," Camavinga said. 

"I'm not worried about him. On a day-to-day basis, he seems at ease, and calm."

The attacking burden may fall upon the shoulders of Mbappe, who has scored the most goals (43) in Europe's top five leagues in 2022), but Camavinga does not expect France to lower their expectations.

"No, not necessarily, we also have a lot of big players in the squad. There are other leaders in the squad too," he added. "We're not going to lower our objectives. Of course, it's a hard blow.

"But we're not going to rest on that. We're going to continue to fight with the big squad that we have."

France centre-back Ibrahima Konate echoed team-mate Camavinga's sentiment as he urged Les Bleus to battle through injury issues in the Middle East.

"It hurts us. It's a hard blow for the French team but our objective doesn't change, it's always the same," the Liverpool defender said. 

"That's part of football. We have to deal with it and move on, not look back. We have a match coming up very quickly. If we start looking at these things, it could be complicated."

Karim Benzema insisted it was not in his nature to "give up" as he was forced to concede his World Cup dream with France was over.

A quadriceps problem in his left thigh has flared up and left the 34-year-old resigned to packing his bags rather than contributing for Les Bleus in Qatar.

He won the highly prized Ballon d'Or award last month, recognition of his spectacular form last season, but Benzema will be on the outside looking in on football's biggest show after suffering a setback in France's training session on Saturday.

It had been his first full on-pitch activity with the France squad during the pre-tournament camp, with Benzema having been determined to prove his fitness before the team's opening game against Australia on Tuesday.

He had been bothered by muscular fatigue in the left quadriceps while with Real Madrid in recent weeks, missing several games, and this latest blow may be a recurrence of that problem.

France have the option to call in a replacement for Benzema, who faces around three weeks of recovery. That time span suggests Benzema could have been fit in time to contribute before the end of the World Cup, but it was agreed he should be withdrawn from the squad.

Reports said France would decide whether to summon an additional player on Sunday.

Benzema wrote on Twitter and Instagram: "In my life I never give up but tonight I have to think about the team like I always do, so reason tells me to leave my place to someone who can help our team to have a great World Cup. Thank you for all your messages of support."

International team-mate and fellow superstar striker Kylian Mbappe replied by writing "Force", which translates to "Strength".

France and Barcelona winger Ousmane Dembele was another to send a message of support, as was Presnel Kimpembe, the defender who withdrew from the squad at the start of the week due to his own injury.

Benzema's Real Madrid team-mate Rodrygo, a member of Brazil's squad, wrote: "The best must compete in the best. You will be missed in the World Cup... Good recovery KB9!"

Mauricio Pochettino has hinted Kylian Mbappe may need to leave his Paris Saint-Germain "comfort zone" to develop into a Ballon d'Or contender.

World Cup winner Mbappe, who will look to help France defend their crown in Qatar, has repeatedly been linked with a move away from the Parc des Princes to Real Madrid.

The Spanish and European champions appeared set to lure Mbappe to Madrid on a free transfer ahead of the 2022-23 season, only for the forward to sign a bumper three-year extension with PSG in May.

Further uncertainty clouded the 23-year-old's future as fresh reports of discontent emerged in October, though Mbappe assured his commitment remains in the French capital.

Yet, former PSG coach Mauricio Pochettino suggested the ex-Monaco attacker might have to move on to fully realise his world-class potential.

Pochettino told Spanish newspaper El Pais: "He may be a leader because everyone sees him as the best striker in the world, but today the Ballon d'Or has been won by Benzema, who is French like him. The evolution of Mbappe comes from leaving the comfort zone.

"Renewing for PSG is good for the club and its fans. But Mbappe in the future will have to consider that leaving his comfort zone will bring him closer to fighting for the Ballon d'Or."

Mbappe has found the net 19 times in 20 appearances for PSG this term, a tally only bettered by Manchester City's Erling Haaland (23) among players in Europe's top five leagues.

The PSG star became just the second teenager to score in a World Cup final (after Pele in 1958) at his first major international tournament in 2018, though Pochettino believes Mbappe is still "immature".

"Mbappe is younger than [Lionel Messi and Neymar] and still immature," Pochettino said. "But he has won a World Cup. He is an animal, he has great charisma but still needs to find himself.

"Leo and Ney are total players, they are more responsible although in different ways."

Mbappe will hope to fire France to more World Cup glory as Les Bleus start their campaign in the Middle East against Australia in Tuesday's Group D clash.

Kylian Mbappe is only playing at "40 or 50 per cent" of his full potential, according to Paris Saint-Germain's football advisor Luis Campos.

Mbappe was named Young Player of the Tournament as France won their second World Cup in 2018, and is looking to help Les Bleus defend the trophy in Qatar after making a fine start to the club season.

The forward has found the net 19 times in 20 appearances for PSG this term, a tally only bettered by Manchester City's Erling Haaland (23) among players in Europe's top five leagues.

Mbappe became just the second teenager to score in a World Cup final (after Pele in 1958) at his first major international tournament in 2018, but PSG advisor Campos believes he still has room to improve.

"Mbappe is still only at 40 or 50 per cent of his potential, and I tell him that every day," Campos said at an event in Porto.

"He can still give a lot more because he is a player who has not yet finished his training.

"There is the speed of maturation, that is to say that not everyone evolves at the same rate. Mbappe at 16 was already developed at all levels. 

"Physically, he was very strong and had an understanding of the game worthy of a 26-year-old player."

The decision to schedule the World Cup during the middle of the European club season has attracted criticism after several big-name players – including France defenders Raphael Varane and Presnel Kimpembe – suffered injuries during a congested pre-tournament schedule.

However, Campos feels the timing of the World Cup means most players will be at the peak of their powers, which could make for a special tournament.

"I think it's the biggest competition in the world, at least for me, and for the first time in history the players will be at full speed, with pace and fresher than ever," he continued.

"It will be the most intense FIFA World Cup of all time."

Adrien Rabiot says France must "stay united" if they are to avoid the failures that saw them crash out of Euro 2020 at the round-of-16 stage.

France went into that tournament as world champions and advanced as group winners from a tricky pool that included both Germany and Portugal.

But their campaign was derailed in stunning fashion, as Switzerland scored two late goals to force extra-time from 3-1 down.

Kylian Mbappe then missed the crucial penalty in the shootout, as France were knocked out amid rumours of dressing room discontent.

Rabiot's family were reportedly involved in dissension too, with his mother allegedly clashing with the relatives of Paul Pogba and Mbappe after the Switzerland defeat.

Their disappointing tournament sparked memories of France's spectacular capitulation at the 2010 World Cup, where Les Bleus were blighted by a number of controversial incidents and failed to make it out of the group stage.

Rabiot acknowledged France cannot afford to self-destruct as they have in the past if they are to retain their World Cup crown.

"We have to stay united," Rabiot told reporters. "[We need to] try to have as few things as possible that interfere with the group.

"It is essential to have a serene climate. We have the potential to do much better than at the Euros."

The Juventus midfielder was not selected to France's squad for their 2018 triumph and he wants to make an impression at his first World Cup in Qatar.

"The [2018] World Cup was a big disappointment," Rabiot explained. "I worked a lot to be there in 2022.

"I take this as a chance and I'm going to be able to express myself."

France kick off their tournament against Australia on Tuesday, before also facing Denmark and Tunisia in Group D.

Neymar revealed he and Paris Saint-Germain team-mate Lionel Messi joke about a potential World Cup final between Brazil and Argentina in Qatar.

Neymar and Messi, alongside Kylian Mbappe, form a fearsome front three for PSG, one that has fired them to a five-point lead at the top of Ligue 1 and reached the Champions League knockout stages.

But that alliance will be temporarily halted until PSG's next game on December 28, as the three superstars bid to win the World Cup for their respective countries.

While he was highly complimentary of Messi and Mbappe, Neymar jokingly hinted that he fancies his Brazil side's chances in a potential match-up with Messi's Argentina.

"We don't discuss it very much," Neymar told The Telegraph. "But sometimes we joke about crossing paths with each other in the final.

"I tell him [Messi] that I'll be champion and win against him and we have a good laugh.

"Playing with him and Kylian is a huge pleasure. They're two greats, with Messi long considered the best in the world.

"Kylian is a young player who’s been growing and showing his potential and still has a lot to grow. It's always great to play alongside the greats, I've always preferred that because the chances of winning are higher."

Neymar feels Brazil are one of the favourites, but also highlighted a number of other teams he believes are capable of making the final on December 18.

"The World Cup is full of surprises," he explained. "You get teams that unexpectedly get very far even in the competition even if many don't believe in them.

"But I believe the favourites are Argentina, Germany, Spain and France. I think those four along with Brazil are fully capable of reaching the final."

At the age of 30, the Qatar World Cup could be Neymar's last attempt at glory with Brazil, having fallen short in his two previous experiences at international football's premier tournament.

One of those was particularly painful, when Neymar suffered a back injury in a victorious quarter-final meeting with Colombia at Brazil's home tournament in 2014.

Neymar was ruled out of the semi-final with Germany, a match Brazil went on to lose by a humiliating 7-1 scoreline.

But the former Barcelona forward says his career would not feel incomplete if he were to never win the World Cup, saying: "No, in my career I've achieved things beyond my imagination.

"So, if it ended today, I would still be the happiest person in the world."

The number 10 jersey that Neymar dons for Brazil is steeped in history, having been worn by Selecao legends like Pele, Ronaldinho and Zico.

Neymar does not experience the pressure that could come with following those Brazilian idols, declaring: "I don't feel under pressure, quite the opposite.

"I'm happy to be able to wear the number 10 on the Brazilian team and make history. It's a great pride and honour to be part of the group of players that wore it and I only feel happiness about it."
