Christophe Galtier was grateful to have Lionel Messi back as the World Cup winner scored in Paris Saint-Germain's 2-0 win against Angers on Wednesday.

The Argentina captain made his first appearance back for his club since lifting the trophy last month, and with PSG only leading 1-0 against Ligue 1's bottom club after Hugo Ekitike's early goal, Messi made the game safe in the 72nd minute as he ran onto a pass from Nordi Mukiele before finishing into the bottom left corner of the net.

Speaking after the win, Galtier thanked the fans for their celebration of Messi's achievement in Qatar, despite Argentina beating France in the World Cup final.

"Thank you to our supporters for welcoming him in the way that they did. That means a lot to him. Our fans also got behind him when the game was difficult," the PSG head coach said.

"Messi has recovered well. He has had quite a few training sessions back with us now. He seemed lighter and in very good physical shape.

"Of course, the team is different with and without Messi. He also scored an important goal for us tonight and we all know that he loves scoring goals, he is the sort of player who needs goals.

"I spoke to him at half-time to see how he felt and he said he felt good... It is important to have Messi back at the heart of our game. The fact that he played 90 minutes is even better."

Galtier also explained why he opted for a 3-4-2-1 formation, emphasising the importance of his team being able to show flexibility as they extended their lead at the top of the table to six points following Lens' draw with Strasbourg.

"It was for this game, based on how we prepared," he said. "I felt it was not going to work in the way we had prepared. I also spoke to my players and my staff in terms of our options, and we took a different one.

"The team performed very well in this system at the start of the season in big games. That is how it went tonight. It is important for a team like Paris Saint-Germain, for my players, and also, for me and the staff to have options, as well as the ability to switch from one system to another."

Kylian Mbappe spoke from the heart when defending Zinedine Zidane from sniping by French Football Federation chief Noel Le Graet, according to Paris Saint-Germain boss Christophe Galtier.

Le Graet is facing calls to quit as FFF president after coming under fire for a bizarre comment about France great Zidane, and allegations about his leadership.

The 81-year-old Le Graet told RMC he did not "give a toss" where the 1998 World Cup winner went in his next coaching job, and added he would not answer the phone to the former midfielder.

Former Real Madrid head coach Zidane had been thought to be a likely contender for the France post if coach Didier Deschamps had decided to leave after the recent World Cup in Qatar.

It was instead announced Deschamps would be staying on until the 2026 World Cup, signing a new contract.

France star forward Mbappe delivered a clear and powerful rebuke to the federation president, writing on Twitter: "Zidane is France, we don't disrespect the legend like that..."

While Galtier did not wish to pile on further criticism of Le Graet, the PSG head coach also made it clear he did not agree with the comments from the veteran federation boss either, and understood why Mbappe took his stance.

"Zinedine Zidane deserves the respect of everybody," Galtier said in a PSG press conference on Tuesday.

"He was an extraordinary player for the France team and a brilliant coach who has won the Champions League three times.

"The words that were said have created a strong reaction. I'm not going to comment on those words. I will simply say Zinedine Zidane deserves huge respect from everyone."

Galtier added: "Kylian Mbappe is a great guy. I haven't spoken to him about this. That is away from the context of PSG.

"He expressed himself in his own way with his heart, so that is what he said, and I am not surprised that Kylian Mbappe wanted to defend Zinedine Zidane. I know he has a huge respect for Zinedine Zidane."

The French sports minister Amelie Oudea-Castera has called for change at the top of the FFF, while leading agent Sonia Souid accused Le Graet of improper conduct.

In an RMC interview, Souid outlined how her belief was that in their dealings from 2013 to 2017, Le Graet saw her as an object of his sexual desire.

Le Graet and the FFF did not immediately respond to Souid's allegations.

Kylian Mbappe would be taking on "a huge responsibility" if he becomes the new France captain, after Hugo Lloris retired from international football.

That is the verdict of Paris Saint-Germain head coach Christophe Galtier, who steered clear of either recommending the role to Mbappe or putting any pressure on national coach Didier Deschamps.

At the age of 24, Mbappe has already won 66 caps for Les Bleus, scoring 36 goals in the process.

He won the World Cup in 2018 and scored a hat-trick against Argentina in the 2022 final but painfully finished on the losing team.

PSG striker Mbappe appears an obvious candidate, but he may not aspire to the captaincy, which Lloris held for 10 years.

Manchester United defender Raphael Varane is another strong contender for the role, according to reports in France, having served as vice-captain at the World Cup.

Galtier said on Tuesday: "I'm not the national team coach. I'm not going to get involved in the France captain discussion. Sometimes, the France captain is of a certain age with a certain number of caps.

"Kylian Mbappe has got many under his belt and many incredible performances. I haven't spoken to Kylian Mbappe about whether he will be the France captain or not.

"Of course, that is a huge responsibility. It is not me who will decide who the captain will be. Even without the armband, he is a leader."

Christophe Galtier conceded his Paris Saint-Germain players may have underestimated Chateauroux in their Coupe de France clash on Friday.

PSG ultimately won the tie 3-1 at Stade Gaston Petit thanks to late goals from Carlos Soler and Juan Bernat, but their third-tier opponents had given them a tough battle until then.

With no Lionel Messi, Neymar or Kylian Mbappe, PSG relied on 20-year-old Hugo Ekitike to fire them in front early on, before Natanael Ntolla equalised prior to half-time via a deflection off El Chadaille Bitshiabu.

Late pressure finally bore fruit for Galtier's side, though, as Soler and Bernat both struck, and the PSG head coach was just happy to be through to the last 32.

"There is the satisfaction in being qualified," he said. "Games like this are difficult. The start was in line with what I expected, with the opener. Afterwards, my team was cut in two and that gave Chateauroux a lot of hope.

"Did we think things were going to be easy? Maybe."

The former Lille and Nice boss made seven changes to the team that started the 3-1 loss at Lens last time out, including teenage trio Ismael Gharbi, Bitshiabu and 16-year-old Warren Zaire-Emery.

Although it took the introduction of Sergio Ramos and Fabian Ruiz in place of Bitshiabu and Gharbi just after the hour for the visitors to take charge, Galtier was pleased with the performances of the youngsters, having anticipated a tough night with several first-team players missing following the World Cup.

"I was satisfied with the young players," he said. "They were serious and on pace. I really liked Ismael in the game. Warren was of a good level. El Chadaille was unhappy [about the goal against].

"I expected a complex game with the absence of many players and the different states of form. We will see which ones we will recover for Angers [on Wednesday]. 

"Teams that have had a lot of players at the World Cup are struggling to restart at the start of the year. We will quickly have to refocus on the objectives."

Paris Saint-Germain left out their biggest stars and survived a scare to progress in the Coupe de France, earning a 3-1 win at Chateauroux on Friday.

An early goal from Hugo Ekitike was cancelled out by Natanael Ntolla before half-time, and PSG had to wait until the 78th minute for Carlos Soler to bundle home for the Ligue 1 side before Juan Bernat added some gloss to the score late on.

Christophe Galtier included 16-year-old Warren Zaire Emery in his much-changed starting line-up, with no Lionel Messi, Neymar or Kylian Mbappe as Ekitike, Pablo Sarabia and Soler were selected in attack.

Chateauroux, who play in the third tier of French football, belied their lowly position of 14th in the Championnat National with a determined showing against their celebrated opponents, but PSG ultimately made it through to the last-32 stage.

The visitors took the lead in the 13th minute when Ismael Gharbi's first-time ball from the edge of the box into the path of Ekitike allowed the young striker to finish neatly in off the left post with the outside of his right foot.

Jonathan Mexique went close for the home side with a close-range shot in the 26th minute that was deflected over by a diving Vitinha, while Paul Delecroix made a good save down to his left from a Gharbi volley shortly after.

The scores were level eight minutes before the break though after neat work down the left ended with former Lille and Saint-Etienne striker Nolan Roux pulling the ball back for Ntolla, whose goal-bound shot was deflected past Keylor Navas by 17-year-old PSG defender El Chadaille Bitshiabu.

Galtier called for more experience in the second half as Sergio Ramos and Fabian Ruiz came on just after the hour, and the coach eventually saw his team re-take the lead as Vitinha stood up a cross to the far post that allowed Ekitike to head at goal, with Soler following up from Delecroix's initial save.

Bernat made it 3-1 in stoppage time after racing onto a ball from Ruiz and firing low and hard across Delecroix to seal the victory for PSG.

Neymar's training absence on Thursday was "scheduled" and he will miss Paris Saint-Germain's Coupe de France tie with Chateauroux, Christophe Galtier confirmed.

The forward suffered an ankle injury in Brazil's opening World Cup match, missing the final two group-stage games, though he returned to score in both of the Selecao's knockout ties as they crashed out in the quarter-finals to Croatia.

Neymar returned to PSG and featured in their first Ligue 1 fixture against Strasbourg, but he was given a second yellow card for a dive in the 62nd minute as a late Kylian Mbappe penalty snatched a 2-1 victory.

He was therefore suspended for PSG's 3-1 defeat to Lens on Sunday, their first loss of the season, and he was a notable absentee from training on Thursday.

Galtier insisted Neymar not training was planned and he also confirmed the 30-year-old will play no part against Chateauroux in the Coupe de France on Friday.

"As for Neymar's absence in training that had been scheduled, as it was for all of the players who went to the World Cup," PSG boss Galtier told reporters.

"They were assessed by our medical staff and performance team.

"We decided as a group that Neymar, with everything he has experienced with his ankle problem, that he needed time for his ankle to recover."

Asked whether Neymar was expected to miss the following game too, a Ligue 1 home meeting with Angers on Wednesday, Galtier replied: "Just tomorrow."

Neymar was visibly upset after Brazil's penalty defeat to Croatia, with his hopes of winning a World Cup now looking slim with the next tournament occurring when he will be 34.

However, Galtier is not concerned about the former Barcelona man, saying: "I'm not at all worried about Neymar.

"Based on what he has been doing since the start of the season, he is full of desire to play and he wanted to play in the league game but was suspended. He was very disappointed.

"We are lucky to have a very committed Neymar here, but we need to keep an eye on him physically."

After Brazil's shock exit in Qatar, Argentina and France went on to play what many are calling the best World Cup final ever, with PSG's Mbappe and Lionel Messi playing starring roles as La Albiceleste ultimately won on penalties following a 3-3 draw after extra time.

Galtier hopes Messi receives a warm reception in Paris on his return having beaten France in the final, while saying Mbappe has not changed after winning the tournament's Golden Boot and scoring a hat-trick in the final.

"He [Messi] will not play tomorrow," Galtier explained. "Having discussed it with him, we want him to be ready for the following game.

"I hope he will be celebrated by our supporters. Leo Messi is a Paris national player and World Cup winner. We are lucky to have a player like Messi here.

"We also need to appreciate we have [Mbappe] at the club. Just like Messi, he had a brilliant World Cup.

"Kylian Mbappe quickly wanted to get back into competitive football after the World Cup. I feel he is a very intelligent guy who learns quickly, and he knows the general consensus around him has changed.

"He is a player with huge personality and character who is capable of managing that. We have Kylian Mbappe here on a daily basis and he is the same as before."

Paris Saint-Germain did not lose to Lens simply because Lionel Messi and Neymar were unavailable, according to captain Marquinhos.

The Ligue 1 leaders slipped to a first loss of the season, with goals for Przemyslaw Frankowski, Lois Openda and Alexis Claude-Maurice ensuring a 3-1 defeat at Stade Bollaert-Delelis on Sunday.

Christophe Galtier's side were missing key personnel, with Messi only just returning from a post-World Cup victory break and Neymar banned after a red card against Strasbourg.

However, Marquinhos refused to cite the lack of the former Barcelona pair, instead suggesting PSG were simply outclassed by a superior opponent.

"They are great players who make the difference," Marquinhos told Amazon Prime Video. "But we have already won without them.

"We have to find the cohesion of our team again. I think Lens were more efficient, especially in the first half. They won the duels which made the difference.

"We had opportunities to come back, to score, but we weren't able to be as efficient as they were."

PSG's defeat was their first in Ligue 1 since March last year against Monaco, ending a 25-game streak without a loss in the top-flight.

It marked a first competitive reverse as PSG head coach for Galtier, after succeeding Mauricio Pochettino ahead of this campaign, and he felt his side gave an uncharacteristic account of themselves.

"Lens deserve this victory," Galtier said. "I had a hard time recognising my team. We lacked cohesion, we collapsed as the match progressed.

"We gave a lot of space away, we made a lot of technical errors. There was a lot of surprising wastefulness from my boys. They don't give me that habit usually."

Paris Saint-Germain head coach Christophe Galtier says the club will only make signings in January if players leave the Ligue 1 leaders.

PSG needed a stoppage-time penalty from Kylian Mbappe to seal a nervy 2-1 win over Strasbourg in their first game after the World Cup on Wednesday.

That ensured they will end the year seven points clear at the Ligue 1 summit, and Galtier does not envisage the club dipping into the transfer market when the window opens on Sunday.

"I am very happy and very satisfied with the squad I have," he said ahead of his side's visit to Lens on New Year's Day.

"There will be no arrivals if there are no departures. There are no players who have asked to move. It means that the players are good here. 

"It's a long period, we have to see how things evolve. 

"A defender is not needed. We have El Chadaille Bitshiabu, who played against Strasbourg. He has enormous potential. We place a lot of hope in him. 

"Going for a defender would be blocking space for him. We want to promote our local talents."

Mbappe's last-gasp intervention against Strasbourg marked his swift return to domestic action following France's defeat in the World Cup final to Argentina on December 18.

Despite scoring a hat-trick for Didier Deschamps' side, Mbappe and his international team-mates came up short as Les Bleus were beaten on penalties in the showpiece game of Qatar 2022.

Speaking after the game against Strasbourg, the 24-year-old acknowledged the pain of France's loss in Doha will stay with him forever, but Galtier does not expect his disappointment to impact on his performances for PSG.

"If I understood his statement correctly, he said it will take time to digest the fact of not having lifted the World Cup for the second time. It's normal," he added. 

"But showing such a desire to win reflects his state of mind and his mentality as a very high level champion. 

"He was still this morning very dynamic, very happy. He is a player who is growing every day. How lucky we are to have a player like that."

Kylian Mbappe was the "trigger for victory" in Paris Saint-Germain's defeat of Strasbourg as head coach Christophe Galtier praised the forward for putting World Cup heartbreak behind him.

The attacker won and converted a stoppage-time penalty to snatch a late victory against Strasbourg in Ligue 1 on Wednesday after Neymar had been sent off.

Mbappe's intervention came 10 days after he scored a World Cup final hat-trick for France, only to lose out on a second successive title as Argentina won on penalties.

However, Galtier praised the 24-year-old's fortitude, highlighting his role as a talisman for the champions and suggesting he will pick up where he left off with his World Cup form.

"I think he is on the level of what he did in Qatar," the coach said. "He's benefited from a few days off. Despite the sadness, he had an exceptional tournament, and his recovery means he's been on the pace.

"Since his return, he was determined to play our next two matches. He was the trigger for victory when it was tough. He has taught the whole team with his selflessness."

Neymar's dismissal, for consecutive yellow cards around the hour mark, proved the biggest moment of the match before Mbappe's late heroics.

The Brazilian was booked initially for catching Adrien Thomasson in the face with a trailing hand.

He was then dismissed for simulation.

Galtier acknowledged the second offence was the right call by the officials but felt the first was harsh, particularly after Neymar was on the receiving end of several unpunished challenges.

"I can understand the anger on his part," Galtier added. "I regret that the excessive commitment was not sanctioned more severely. I can understand the simulation, it deserves a yellow.

"But a few minutes before, he takes a bad blow. His first yellow is very severe compared to the number of challenges suffered by Neymar, and not small challenges."

Christophe Galtier insists there is no risk involved in throwing his World Cup stars straight back into Ligue 1 action.

The likes of Neymar, Kylian Mbappe and Achraf Hakimi are poised to face Strasbourg on Wednesday as the French top flight cranks into gear once more.

A six-week break for domestic duty has seen PSG's star names experience the roller coaster emotions and intense scrutiny of national team duty at the highest level.

Hakimi helped Morocco make history by becoming Africa's first semi-finalists, while Neymar had an injury-plagued campaign that ended with Brazil's defeat on penalties to Croatia in the quarter-finals.

Mbappe then experienced the cruellest of fates when he became just the second man to hit a hat-trick in a World Cup final, only to finish as a runner-up after France's spot-kicks loss to Argentina.

Ten days will have passed since that loss at Lusail Stadium when Mbappe steps out to face lowly domestic rivals, and Galtier said: "I don't think there is a risk.

"They wanted to get to play in these very important league games. Of course, we will need to manage things in the coming weeks to see how Achraf Hakimi and Kylian Mbappe cope.

"We are thinking about that and we will need to find the fight time for them to rest."

That rest is likely to come sooner rather than later, given PSG have Champions League commitments from February, but for now Galtier believes his players are reliable judges of their readiness to play.

Head coach Galtier saw PSG pull five points clear of second-placed Lens before the World Cup, and with a trip to Stade Bollaert-Delelis coming up on Sunday, the Strasbourg game might be seen by outsiders as a soft landing before the first big test arrives.

Galtier sees it as nothing of the sort, warning the 19th-placed visitors are "playing for their lives" and suggesting PSG's previous form counts for nothing.

Strasbourg have won just one of 15 league games to date this season, while unbeaten PSG have 41 points from the same number of matches.

Strasbourg also have the highest expected goals against total in Ligue 1 this season (28.52 xGA), signalling their opponents have been able to create a high number of good goalscoring chances, while PSG have the lowest (15.06 xGA) and have shipped just nine goals.

PSG are unbeaten in 31 home games against Strasbourg in Ligue 1 (W24 D7), too, the longest such streak against a specific opponent by a Ligue 1 team without ever losing.

On paper, therefore, there is little for Strasbourg to cling to. PSG have not lost at home in their past 36 home games spanning all competitions (W30 D6), since losing to Manchester City in the Champions League in April of last year.

Perhaps the only saving grace for the team from Alsace is they will not have to face World Cup winner Lionel Messi, who has been granted an extended break by PSG.

Galtier knows anything less than three points would be a disappointment, which is why he is preparing the team with the utmost seriousness and backing them to respond.

"If you just focus on the table that would be a big mistake," Galtier said.

"We are starting from scratch. That is what I said to my players. We had a very good start to the season and we know why that was. The players a had a serious approach. They were demanding. They showed determination and humility.

"They want to achieve something together and all of us need to be in the same mindset tomorrow come kick-off."

Lionel Messi will not return to Paris Saint-Germain until early January, but Kylian Mbappe is set for an immediate return to Ligue 1 action against Strasbourg on Wednesday.

Head coach Christophe Galtier revealed Messi will miss the Strasbourg game, and Sunday's trip to Lens, after being given dispensation to stay in Argentina for an extended post-World Cup break.

Messi headed home after Argentina's Qatar 2022 triumph, to be feted for his leading role in the team's triumph after their dramatic win on penalties against France in the December 18 final.

Mbappe, who hit a hat-trick for France in that game but still finished as a runner-up, has returned to full training with the capital club and looks set to line up at the Parc des Princes against Strasbourg, with Brazil's Neymar and Marquinhos and Morocco's Achraf Hakimi also available after rejoining Galtier's group.

Galtier said: "There are individual cases with the players who went very far. Achraf Hakimi played in every game at the World Cup for Morocco. He was in the team of the World Cup.

"He wanted to get back as quickly as possible, as did Kylian Mbappe. He also turned in some brilliant performances and was the top goalscorer at the World Cup.

"After speaking to him and all my different teams who stayed in regular contact with the players, Kylian Mbappe wanted to join back up with us pretty quickly.

"There could be a time when Achraf Hakimi and Kylian Mbappe need to rest. Not necessarily physically, but definitely mentally.

"As for Leo Messi, who had a brilliant tournament, given they won the competition, he went back to Argentina for the celebrations. We made the decision to give him until January 1, so he will be back here with us on the second or third to get back into the swing of things after 13 or 14 days off."

Reports have claimed Messi, who scored seven goals and won the World Cup's Golden Ball prize, has agreed a contract extension with PSG, who will be hoping to get that deal completed soon after his return to France.

An ankle blow for Neymar during the World Cup is no longer troubling the former Barcelona forward, Galtier said.

He returned to France on December 22, and Galtier said: "He has been working outside as normal without any restrictions. Physically he is fine, and mentally he is looking forward to playing."

The PSG boss dismissed any suggestion of a possible problem emerging between Messi and Mbappe, after Argentina's post-final celebrations in the dressing room saw goalkeeper Emiliano Martinez mock the PSG and France striker.

Galtier suggested all the blame for that episode was with Martinez.

"What happened in the celebrations belongs to the Argentinians, and it is not down to me. What matters to me is what I saw in the final and on the sidelines I saw Kylian Mbappe and Lionel Messi embrace," Galtier said.

"There is a lot of respect between them. They have an exemplary attitude after the games. And of course, [Messi] needs to be congratulated for the trophies, and the Argentina coach as well.

"So I would focus on the relationship between them. It wasn't Leo Messi winding anybody else up. What I saw after the final, what I have experienced, is there is no reason to mix these things up because the goalkeeper's behaviour is down to him.

"What matters to me is the relationship between the players. Kylian Mbappe had a very good attitude, despite losing. Of course he was very disappointed, but he did that in a classy way. He congratulated Leo Messi and that is a very good thing for the club and for the team."

For the players who returned from the World Cup disheartened, Galtier says throwing themselves back into club duty has been a welcome escape.

"When they came back, our medical and coaching teams have spoken to the players to understand how they are feeling, because they are top-level footballers who enjoy playing and training to be able to play," Galtier said.

"There is no better remedy than to go back to your club where there is a very good atmosphere, a good feeling. Everyone is showing their commitment based on the training sessions I've been involved with."

Christophe Galtier believes Kylian Mbappe's return to Paris Saint-Germain training just three days after a World Cup final defeat is a "strong signal."

Mbappe scored a hat-trick in Sunday's final at Lusail Stadium, twice converting from the spot while also firing home a superb volley as the game ended 3-3 after extra time.

It was Mbappe's team-mate Lionel Messi who ultimately lifted the trophy, though, after Argentina won the penalty shoot-out 4-2.

While Messi returned to Argentina to celebrate, Mbappe was back in PSG training on Wednesday as he attempts to overcome his Qatar heartbreak.

The forward will turn his attention back to the remainder of the season, with PSG holding a five-point lead at the top of Ligue 1 and facing a huge Champions League meeting with Bayern Munich in the round of 16.

Galtier feels Mbappe's decision to get stuck back in with PSG instead of taking extra days off shows what he is made of. 

"I'm very happy to see him," Galtier told PSG TV. "Kylian had a great World Cup. This return is also a strong signal to everyone.

"A player who may have been disappointed not to lift the most beautiful of trophies, even if he was top scorer at this World Cup [with eight goals].

"He wanted to get back in contact with the group very quickly and prepare for the deadlines which are coming up very quickly. 

"We are very, very happy to see him."

Achraf Hakimi, who enjoyed an excellent World Cup as Morocco got further than any African nation in history, also returned to training with the Ligue 1 champions on Wednesday.

PSG return to competitive action against Strasbourg on December 28.

Christophe Galtier believes success in the Champions League should not define his ongoing project at Paris Saint-Germain.

PSG have been dominant force in France over the past decade, winning eight Ligue 1 titles while also capturing the Coupe de France and Coupe de la Ligue on six occasions.

But the coveted Champions League crown has continued to elude Parisian giants, who came closest to landing it when they lost 1-0 to Bayern Munich in the 2020 final.

PSG will face Bayern once more in the last 16 of this season's competition, but head coach Galtier thinks his future at the club should not depend on their performances in Europe.

"There are 10 teams that every season aim to win the Champions League, and only one achieves it," he told Marca. "And then, the other nine who have not succeeded, do we have to fire their coaches? No.

"It's very difficult to win the Champions League. I'm not looking to protect myself, but the big European clubs have this goal and don't change everything because they don't win it.

"There are several examples. Atletico [Madrid] reached the final twice and when they did not win, the club continued to believe in [Diego] Simeone and his sporting project. The same goes for Pep Guardiola. [Manchester City] haven't won yet, but the club still believes in their ideas.

"I think it would be a mistake to change PSG's sports project if the Champions League is not won. I think it's a process, obviously not a 10-year one, but what shouldn't be is that if we don't win this year, we change everything."

Despite being unbeaten in six matches, PSG only advanced to the knockout stages as group runners-up for a second successive season, as Benfica snatched top spot in Group H by virtue of scoring more away goals.

Galtier's side conceded seven goals - with only RB Leipzig (nine) and Eintracht Frankfurt (eight) shipping more against the teams that progressed to the last 16 - and the head coach insists they must tighten up to embark on a long run in the competition. 

"We have conceded too many in the Champions League," he added. "Obviously, there is a difference in level between the Champions League and our championship. But if we want to go far in the Champions League, we must improve our defensive level.

"Nothing is easy in the Champions League. In addition, no one in the analysis has taken into account the difficulty of the calendar this season. It is the first time in the history of football with such a compact and difficult calendar.

"Practically every week, there were Champions League games. I think that's why some teams that normally made it past the group stage haven't. We have played in three and a half months what we normally played in four or five months."

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."

Christophe Galtier says Kylian Mbappe is not "above the club" after he made the "difficult decision" to stay at Paris Saint-Germain.

Mbappe had looked set to join Real Madrid when his contract expired at the end of last season, but instead signed a new three-year deal with the Ligue 1 champions.

It was reported last month that the France international wants to leave PSG in January despite only committing his future to the club in May.

Galtier says Mbappe, who is currently preparing to play for the defending champions at the World Cup in Qatar, "embodies the project" at the Parc des Princes but is not more important than any of his team-mates.

The PSG head coach said during an appearance on Rothen ignites on RMC: "He embodies the project, there can be no doubt.

"But when I say that he embodies the project, it is not that he is above the club. Kylian is at the same level as all the other players.

"On the same level as Leo Messi, who has an incredible career, who is the greatest player in the history of football. Kylian is on the same level as Neymar."

Galtier acknowledged Mbappe had come to a "difficult decision" to remain in the French capital, adding: "Obviously he is in love with Paris Saint-Germain, but he had a very attentive eye on Real Madrid.

"He made the decision to stay. Thank you for Ligue 1, for PSG, for the players and for me. He made a strong decision and he must be respected for that. He is respectable."
