Yunus Musah became the first teenager to be named in the United States' starting lineup for a World Cup match ahead of their Group B opener against Wales on Monday.

Having missed out on qualification for the tournament in Russia four years ago, Gregg Berhalter's side marked their return to the finals at the Ahmed Bin Ali Stadium, against a Wales side featuring at just their second World Cup.

Musah, who also made his senior international debut against Wales in 2020, is now the youngest player to start a World Cup match for the USA, aged 19 years and 358 days.

The Valencia midfielder also becomes the first LaLiga-based player to represent the Stars and Stripes at the finals, while 10 of the starting XI play their club football in Europe - the team's highest total in a World Cup lineup.

Musah was selected to partner Tyler Adams in midfield, with the Leeds United man – aged 23 years and 279 days – becoming the USA's youngest World Cup captain since Harry Keough in 1950.

Berhalter, who becomes the first person to represent the Stars and Stripes at the World Cup as a player and coach, began with Matt Turner in goal behind a back four of Sergino Dest, Walker Zimmerman, Tim Ream and Antonee Robinson.

Adams and Musah were selected to anchor the midfield behind Timothy Weah, Weston McKennie and Christian Pulisic, with Josh Sargent starting as a lone striker.

Meanwhile, Gareth Bale – at least temporarily – drew level with Chris Gunter's record of 109 Wales caps, with the full-back being named on the bench by Rob Page.

Wayne Hennessey was preferred to Danny Ward in goal behind a back three of Chris Mepham, Joe Rodon and Ben Davies.

Connor Roberts, Ethan Ampadu, Aaron Ramsey, Harry Wilson and Neco Williams comprised a five-man midfield, with Dan James providing support to Bale in attack.

Gareth Southgate revealed Harry Maguire was substituted in England's 6-2 win over Iran due to illness rather than injury.

Maguire's inclusion in Southgate's World Cup squad has been fiercely debated after he fell down the pecking order at Manchester United, but he produced a solid performance as England began their Group B campaign in scintillating fashion on Monday.

The defender's aerial presence troubled Iran throughout, and he claimed an assist by nodding down a corner for Bukayo Saka to put England 2-0 up with a brilliant volley in the first half.

Maguire was then replaced by Eric Dier after appearing to go through concussion checks after the break, but Southgate moved to ease any fears regarding his condition after the win.

"Harry Maguire felt ill. [He] flagged it before the [first Iran] goal," Southgate said. "There was no point carrying on, but other than that, no causes for concern."

Writing on Twitter, Maguire said: "I felt unwell in the second half so came off as a precaution. Looking forward to Friday."

Meanwhile, a total of 24 minutes of stoppage time were indicated throughout the game after Iran goalkeeper Alireza Beyranvand suffered a nasty head injury in an early collision with team-mate Majid Hosseini.

While Beyranvand was eventually replaced by Hossein Hosseini, Iran attracted criticism for their initial decision to allow the visibly dazed goalkeeper to continue following the incident.

However, head coach Carlos Queiroz looked to absolve his medical staff of any wrongdoing after the match, saying a broken nose was originally thought to be the extent of Beyranvand's injury.

"We thought he could keep going," Queiroz said. "It was not clear but, one minute after, the player was not able to keep going. 

"He suffered a serious concussion and is on the way to the hospital to have final examinations. 

"That's why the delay happened, because there was doubt between the broken nose and the concussion."

Late goals from Cody Gakpo and Davy Klaassen gave the Netherlands a 2-0 win over Senegal in their World Cup return at the Al Thumama Stadium on Monday.

The Oranje had produced a lacklustre performance in their first World Cup match since the 2014 tournament in Brazil, but secured all three points.

With just six minutes of regulation time left on the clock, Gakpo raced into the box and rose in front of Edouard Mendy to meet Frenkie de Jong's cross with a header to break the deadlock.

Louis van Gaal’s side were not convincing, but they had a second goal deep into stoppage time when Klaassen slotted home right at the end of a disappointing Group A contest.

Poland goalkeeper Wojciech Szczesny is hoping he can help star striker Robert Lewandowski achieve his ambitions on the international stage.

Lewandowski will spearhead the Polish challenge at the World Cup in Qatar, starting with Tuesday's Group C encounter with Mexico.

The Barcelona striker has enjoyed a glittering club career, most notably at Bayern Munich with whom he won the Champions League in 2020, but has found success harder to come by with the national team. Lewandowski is Poland's record goalscorer with 76 in 134 appearances – including nine in their qualifying campaign – but has never scored at a World Cup.

Juventus goalkeeper Szczesny said: "I think it's important for him, he is very motivated.

"No-one doubts that Robert is one of the best players in the world and he would definitely like to see his ambitions come true – not only at his club but also with the national team. We all have the same ambition, not just him."

Szczesny, 32, and Lewandowski, 34, are most likely playing their final World Cup and the former Arsenal man is hoping to enjoy his "last dance".

He added: "I do hope we catch a good rhythm and the music will lead us on. This is definitely my last World Cup, and for some of the other players probably, so it would be great to have something to remember as a success."

He is expecting a tight opener against Tata Martino's men, however.

"They are at a similar level to us and also have some wonderful players," he said.

"We are well prepped, we have analysed them well, but we will need to bring the theory to the pitch. We could win or also lose so it will be an interesting game."

Mexico endured an unconvincing qualifying phase and their form has not improved in recent months with just four wins from their last 11 games.

Expectations are low back home, but Martino insisted that was in contrast to strong belief within the squad.

The former Barcelona coach said: "We always try – regardless of what happens – to be aligned with our whole country.

"We reached the World Cup and we will try to be strong, from what we can control of course. This national team is very strong internally. I don’t know if what happens outside makes us stronger, but what happens internally certainly does."

Carlos Queiroz criticised Iran's supporters after his team were thrashed 6-2 by England in their World Cup opener, advising those who "aren't ready to support the team" to "stay home".

Monday's Group B game was played out in a highly charged atmosphere, as Iran's players refused to sing their national anthem in an apparent show of solidarity with anti-government protestors in their country.

Human rights groups say more than 400 people have lost their lives amid a crackdown on protests in Iran, which began following the September death of Mahsa Amini, a 22-year-old woman who died in police custody after being arrested for her refusal to wear the mandatory hijab.

Jeers were also audible throughout the anthem, while some Iran fans were seen holding signs professing their support for women's rights.

At his post-match press conference, Queiroz called for Iran's fans to offer his players their unconditional backing, characterising sections of their support as "teachers" and "moralists", but it was unclear which section of the supporters he was aiming his criticism at.

"Please, the teachers, the moralists, let the kids play the game. These kids only want to play the game," Queiroz said.

"I hope the players of England and Wales and United States praise them for having the courage to play the game. They are here to bring pride and happiness to the people.

"You don't know what the kids have been experiencing behind the scenes just because they want to play football. Whatever they [the players] say, they [critics] want to kill them.

"Of course, we have our opinions and we will express them in the right time. But I love the game and don't want the players to do something that isn't loyal to the game that is about the entertainment, joy and pride.

"Everyone knows the present circumstances of the environment of my players is not the best environment. They are human beings, they are kids.

"They only have one dream, to play for the country, to play for the people and I am very proud of the way they stand up and keep fighting. 

"I am very proud of what they did but of course in 2014 and 2018 we had full support of the fans. You saw what happened today, the fans who aren't ready to support the team should stay home."

England defender Kieran Trippier heaped praise on the "unbelievable" Jude Bellingham after he played a starring role in the Three Lions' 6-2 hammering of Iran in their World Cup opener.

Bellingham came straight into England's starting XI for the clash at the Khalifa International Stadium on Monday, with Gareth Southgate somewhat catching fans off-guard by naming an attack-minded team.

Their attacking mentality certainly paid off, as did the selection of Bellingham, who opened the scoring just past the half-hour mark with a fine header after a trademark late run into the box, making him England's second-youngest World Cup goalscorer of all time.

While that was the only goal or assist the 19-year-old recorded, Bellingham also played a part in the build-up to Raheem Sterling making it 3-0, and he also released Callum Wilson when the Newcastle United striker set up Jack Grealish's late tap-in.

Bellingham offered drive and purpose to an England midfield often criticised for being too negative, and Trippier was full of admiration.

"Bellingham is an unbelievable player for such a young age," he told BBC Radio 5 Live.

"He is playing at such a high level and he is not afraid. He's got to keep his feet on the ground and keep performing at a high level, like I know he will."

Bukayo Saka also caught the eye for England, scoring two very well-taken goals.

With Bellingham and the Arsenal man both netting, it was the first time in World Cup history that England had two players aged 21 or younger score in a single game, and the impact of the Three Lions' youngsters left Trippier thrilled.

"I'm delighted for them, getting the first goals in the first game," he continued.

"They've all worked so hard. They have great experience for such a young age. Now, it's just about expressing themselves and enjoying it, that's the most important thing.

"I'm 32 years old, and I'm enjoying every game. If I'm playing or not, I will always be ready."

England are next in action against the United States on Friday. Iran face Wales the same day.

Harry Kane says England's players "did their country proud" by opening their World Cup campaign with a commanding 6-2 victory over Iran.

Bukayo Saka scored twice, while Jude Bellingham, Raheem Sterling, Marcus Rashford and Jack Grealish were also on target as Gareth Southgate's side recorded their biggest ever win in their opening match at a major tournament. 

Kane, who provided assists for Sterling and Rashford, saluted his team-mates after they made a real statement of intent in Group B at Khalifa International Stadium on Monday.

"Obviously, [it was a] really good start to the World Cup campaign," the Three Lions captain said in a video posted on Twitter.

"Full credit to the boys. It's never easy getting off to a winning start at a major tournament, and to score six goals shows we're in a really good place.

"There's still a lot of work to do. Of course, we know that there's a long way to go. But overall, [it was] really pleasing. 

"Congrats to Jude for his first England goal, no better place to do it. Bukayo [was] on fire with two great finishes.

"Everyone out there today did their country proud. We move onto the next one now. Let's keep it going for the next game."

England will look to build on their winning start when they face the USA at Al Bayt Stadium on Friday, before taking on Wales at Ahmed Bin Ali Stadium four days later.

Lionel Messi confirmed he is in a great place physically and mentally on the eve of his final World Cup.

The Argentina captain cut a remarkably relaxed figure ahead of Tuesday's game against Saudi Arabia in Doha, repeatedly stressing how much he is enjoying his football as his glittering career enters its final chapters.

Messi caused alarm over the weekend by failing to show for the section of training open to the media, but he was quick to rule out any injury concerns.

He said: "I am feeling very well physically, I'm in good condition. I come here in really good form, both personally and physically. I have no issues whatsoever.

"There were rumours about missing part of training, but no, it was just a precaution, nothing out of the ordinary."

Messi accepts this will be his last realistic shot at World Cup glory, but Argentina's Copa America win last year has lifted an element of pressure and the 35-year-old is determined to depart the global international stage with a smile.

He added: "I don’t know if it’s the best moment in my career but I feel really well and perhaps a bit more mature, always trying to give my best and enjoying everything.

"I think I’m enjoying it much more now. Before I didn’t think about that, I just wanted to play. Now I am trying to enjoy it, but when you play every three days it's sometimes tough.

"Age makes you see things differently, and maybe give more importance to small details. Perhaps before I didn't do that. Now I try to focus on the details and enjoying it is more important than everything else."

The unusual timing of this World Cup has meant a different build-up, but Messi says the pre-tournament nerves remain the same.

"It is different, we usually play the World Cup at the end of the season and we normally have a whole month to prepare," he said.

"Now it's completely different. We've had little time to prepare, but we knew this was the situation. It's always special.

"We expect a tough game, we are aware of this because it's the beginning of the World Cup. We will have to deal with the nerves the best way we can."

Argentina coach Lionel Scaloni also pinpointed his side's 2021 Copa triumph in Brazil – their first major title in 28 years – as a key factor in why they have arrived in Qatar with a quiet confidence.

He said: "The reality is we now play in a much more calm way, we don’t have that weight on our shoulders.

"We are always calm when we go on the pitch and like to feel that freedom. And then it comes down to details. Emotionally we are far more assured and that allows us to play our football.

"But a nation like Argentina always has pressure and if the results are not the best it's obvious that we have criticism.

"We knew about the journey we had to take and we need to keep doing that. We think that’s the best way to do it. We respect the other teams, but we are here to be competitive."

Graham Arnold has refused to mention the names of France's star players, including Kylian Mbappe, ahead of Australia's clash against the World Cup holders.

The Socceroos meet Les Bleus for the second successive finals, with Paul Pogba's deflected late strike sealing a narrow 2-1 win for Didier Deschamps' side in Russia four years ago.

Australia head into their Group D opener having failed to register a clean sheet in 10 previous World Cup matches against European nations, with their only clean sheet at the finals against any opposition coming in a goalless draw against Chile in 1974.

But Arnold, who was the Socceroos' assistant to Pim Verbeek at the 2010 tournament in South Africa, has tried to ease the pressure on his players.

"It's not being disrespectful at all, but I've hardly mentioned the word France," he said. "And I've hardly mentioned any of the players' names because the players know who they are,

"It's one against one, it's 10 blue shirts against 10 yellow shirts, and it's a fight. That's what it is."

Mat Ryan, who is set to become the first Australia goalkeeper to appear at three World Cups, was between the sticks for that 2-1 defeat in 2018.

But despite the reverse, the Socceroos captain believes the experience will serve his side well four years later.

"[We] felt like we almost got a great result there against France, and we felt were quite unlucky," he reflected.

"Something that I learned that day, you've got to have the right amount of respect for the opposition, but don't be in awe of them or be overwhelmed too much.

"We're playing some very good players in a good team, but we're all human out there, and we've got a real good chance to win."

Bukayo Saka savoured a “really special” start to the World Cup after scoring twice in England’s 6-2 thrashing of Iran on Monday.

The Three Lions came into the tournament without a win in six matches, leading to them being consigned to relegation in the Nations League.

But an emphatic Group B victory at Khalifa International Stadium on Monday got them off to a dream start, with Saka on target in each half as Iran were outclassed.

Jude Bellingham, Raheem Sterling, Marcus Rashford and Jack Grealish also got on the scoresheet as Gareth Southgate picked up his ninth major tournament victory as England manager, surpassing Alf Ramsey's total.

Saka's stunning display comes after a disappointing end to his Euro 2020 campaign, when he missed a penalty in the shootout defeat to Italy in the final at Wembley.

The Arsenal winger hit back with a superb 2021-22 season, while he has helped the Gunners open up a five-point lead at the top of the Premier League heading into the break for the World Cup in Qatar.

Saka told the BBC: "We needed that good start.

"We obviously didn't play the best coming into the tournament, so there was a lot of talk and speculation about our form, but we showed everyone today how much quality we have and what we can do.

"I can't describe the feeling, it's amazing. I'm so happy, I'm so proud, and we got the win as well, so it's just a really special day.

"It's amazing to get the win in the end, but we have to be consistent because we have the next game coming up in a few days and we have to win again."

Saka's response to his Euro 2020 heartbreak was described as "impeccable" by club and country team-mate Aaron Ramsdale last week, and the 21-year-old feels at the peak of his powers, adding: "I feel like I'm in a good place.

"I have the support from the fans and I really feel the love from the fans, the coaching staff and my team-mates. That's all I need.

"I feel good and I'm ready to give 100 per cent. I gave that today and I'll continue to do that every time I put the shirt on."

Bellingham was outstanding and scored for the first time for the Three Lions in his first World Cup match to put his side in front with a header.

The 19-year-old quipped said of his goal: "[I] told you I was saving it, didn't I?

"To be honest, I thought it had missed - it took ages to loop into the goal. I told you I wanted to try and score more goals for [Borussia] Dortmund and for England last year.

"To get in there, in the right position, it was a brilliant ball from [Luke] Shaw, and I was just there to flick it away. It's a really proud moment for me."

Gareth Southgate admitted he was left "a bit fed up" by the finale of England's opening World Cup match, despite his side running out comfortable 6-2 victors over Iran.

A brace for Bukayo Saka, plus goals for Jude Bellingham, Raheem Sterling, Marcus Rashford and Jack Grealish, saw the Three Lions kick off Qatar 2022 in style at Khalifa International Stadium.

But despite matching their biggest single-match haul in a World Cup game, set four years ago in a 6-1 win over Panama at Russia 2018, their manager was still left frustrated by their double concession.

Mehdi Taremi's double, the second of which came from a controversial VAR penalty, denied England a record winning margin, and Southgate acknowledged it added a sour note to his side's otherwise superb performance.

"I'm a bit fed up with the end of it, really," he told BBC Sport. "To win by that margin, to play as we did for the majority of the game, you've got to be really happy.

"They dealt with the game really well. It was a sticky first half with lots of stops, but we were a real threat throughout. Our movement was really good.

"But we shouldn't be conceding two goals [at] that stage of the game. We'll have to be right on our game against the United States, it was a great start, but we will have to do better.

"It's a consequence of the scoreline a bit. We just lost concentration and when we play at a slower tempo, we're nowhere near as effective."

Southgate's win takes him to nine at major tournaments, past Alf Ramsey's record of eight, while Bellingham and Saka's goals saw two players under 21 score in the same World Cup game for the first time in England history.

With five different goalscorers overall, the Three Lions boss was delighted with their involvement, adding: "We've got some good players, and today they really delivered. It's a great marker to put down."

In particular, Southgate credited Callum Wilson's assist for Grealish to grab his side's sixth of the match, while warning he must keep his players rooted to the ground ahead of further stern tests.

"Wilson was on," he added. "He could have been selfish but he was thinking of the team even at that moment. I should be more excited, but I've got to keep the team on the right track, where we have to be better."

Robert Lewandowski is dreaming of scoring at a World Cup for the first time in a stark warning to Poland's opening Group C opponents Mexico.

The prolific striker played a huge part in Poland's qualifying campaign with nine goals and four assists, with those 13 direct-goal involvements twice as many as any team-mate.

However, he failed to find the net in 270 minutes of play in his only previous World Cup appearance in Russia four years ago, with Poland finishing bottom of their group.

But after scoring 211 goals at club level since that tournament – 42 more than next-best Kylian Mbappe – the Barcelona star is eager to put that right in Qatar.

"I think about the last World Cup for sure," he said. "To score at a World Cup would be a huge dream and I'm going to do everything for this dream. 

"I hope in this World Cup it will happen. I am glad for everything I have achieved and these memories for the World Cup, so now is the time to enjoy."

Poland's early exit in Russia was nothing new. They have qualified for three of the past five editions but have failed to make it past the group stage since 1986.

That is in stark contrast to first opponents Mexico, who have progressed from their first-round group in each of their past eight finals appearances, last failing to do so in 1978.

Mexico have won their opening match in five of their past six World Cups, though their run of advancing is under threat in a group that also includes Argentina and Saudi Arabia.

Head coach Gerardo Martino is under pressure due to some underwhelming results and performances this year, so much so he has labelled himself "public enemy number one".

"I see people happy a colleague loses or does poorly at work," he added in a fiery news conference in September. "I notice an environment that feels comfortable with this.

"The great concern is what impact this has on the group of players. Every time they have to go out to defend the coach, and in itself it is difficult to be a player."

Mexico's warm-up friendlies culminated in a 2-1 loss to Sweden, with that their third loss in five matches, while Poland have won back-to-back matches without conceding.

PLAYERS TO WATCH

Mexico - Hirving Lozano

No team kept more clean sheets during the third round of CONCACAF qualifying than Mexico (eight), but putting the ball in the net has proved to be more of a problem.

With Raul Jimenez struggling for fitness, having played just three Premier League games for Wolves all season, there is even more onus on Lozano up top.

The Napoli forward is enjoying a good season at club level and already has proven World Cup pedigree, having made a name for himself with his strike against Germany in 2018. 

Poland - Robert Lewandowski

It required more than just Lewandowski's goals alone for Poland to qualify, but there is no denying they need their star performer to be on top form if they are to make an impact.

Lewandowski has made a good start at new club Barcelona, with his 18 goals bettered only by Erling Haaland (23) and Kylian Mbappe (19) across Europe's top five leagues.

Worryingly for Poland, though, their most recent open-play goal at the World Cup came 20 years ago, with each of the past five coming via set-pieces.

PREDICTION

This match at Stadium 974 could go a long way to determining which side joins many people's favourites Argentina in the last 16.

Mexico are ranked 13 places higher than Mexico in the latest FIFA rankings, though our supercomputer prediction model can barely separate the sides.

Poland have a 35 per cent chance of winning, compared to 35.1 per cent for Mexico, with the draw predicted at a 29.2 per cent likelihood.

Bukayo Saka scored twice as England made a flying start to their World Cup campaign by thrashing Iran 6-2 at the Khalifa International Stadium on Monday.

Saka – whose penalty miss proved decisive in the Euro 2020 final last year – netted a stunning volley to help Gareth Southgate's side take a 3-0 lead into half-time, before he doubled up after the break.

With Iran crumbling after goalkeeper Alireza Beyranvand suffered a nasty head injury early on, Jude Bellingham set the tone by scoring his first international goal, while Raheem Sterling prodded home England's third.

Mehdi Taremi denied England a clean sheet with a powerful finish, but substitutes Marcus Rashford and Jack Grealish responded as the Three Lions sent out a message to their Group B rivals despite Taremi scoring a very late second from the penalty spot.

Harry Maguire was a nuisance in the opposition box and saw an early penalty appeal waved away before powering a header against the crossbar in the 32nd minute.

Three minutes later, Bellingham diverted Luke Shaw's hanging cross into the top-right corner with a fine looping header.

With Iran struggling to contain the Three Lions, Maguire nodded a corner into the path of Saka to unleash a fierce volley into the top-right corner and double England's lead.

Southgate's rampant side then made it 3-0 in first-half stoppage time when Sterling cutely diverted home Harry Kane's right-wing cross.

There was no sign of England slowing down after the break, as Saka clinched his brace by cutting inside to drill a low finish beyond Iran substitute Hossein Hosseini.

Taremi denied England a clean sheet by firing in off the crossbar, but substitutes Rashford and Grealish produced composed finishes as the Three Lions extended their lead to 6-1.

There was one last piece of action when Taremi converted from the spot at the end of stoppage time after a VAR check contentiously ruled he was fouled by John Stones.

Aymeric Laporte is confident that Spain have the ability to fight for glory at Qatar 2022 despite falling short of expectations at each of the last two World Cups.

The 2010 champions begin their campaign against Costa Rica on Wednesday, with a tough test in Group E also putting them alongside Germany and Japan.

After victory in South Africa, Spain were eliminated at the group stages four years later in Brazil and lost at the round-of-16 stage to host nation Russia in 2018.

Brazil and Argentina have been tipped as the favourites for glory at this instalment, though Spain are considered among the teams going for glory in Qatar and Laporte is confident Luis Enrique's side have everything required to go all the way.

"All the teams have their strengths, we have an amazing squad, the big majority [of players] compete at the top level in the Spanish league, in England or other places," he told a press conference on Monday.

"We have people very well placed in football, quality, with this boss we are working very well on a tactical leveI. I believe we have everything.

"Then, in these type of games or tournaments, you need luck and there are other factors to be taken into account. But on what depends on us, we will do everything to win."

Laporte was also asked about the injury suffered to France striker Karim Benzema, who has been ruled out of competing at the tournament, which he says is disappointing for the fans.

"In this type of tournament we expect the best to be competing, or many of them," he added. "It is a shame for fans to not see all the best players in the world fighting each other, but those who remain here have a goal and we are going for it."

Jamal Musiala admits being compared to Lionel Messi is a "big honour" as the Germany midfielder prepares for his World Cup bow.

The Bayern Munich star, who played just nine minutes at Euro 2020, has enjoyed an impressive start to the Bundesliga season, scoring nine goals and providing six assists.

The 19-year-old's 15 goal involvements are the most registered by any teenager across Europe's top five leagues and just two shy of Messi's tally for Paris Saint-Germain (seven goals, 10 assists).

"I think it's a big honour to be compared to Messi," said Musiala, who will hope to feature in Germany's Group E opener against Japan at the Khalifa International Stadium on Wednesday.

"He has been playing at the top level for his entire career. It's always hard to compare yourself to others. I prefer to focus on myself and on where I can improve.

"It's important to remain relaxed about what's happening and to not put too much pressure on yourself. You also have to have some fun, and then everything will work out.

Die Mannschaft team-mate Niklas Sule, who was part of the side that exited the group stage in Russia four years ago, hopes Musiala can maintain his solid form at the finals.

"I much prefer to play alongside him, instead of against him. But, I also know how to defend against him," the Borussia Dortmund defender laughed.

"We played a friendly [against Bayern's under-19s side] one time, and you could already see what an exceptional talent he is. He then deservedly moved up to the first team.

"I don't want to praise him too much, because I don't want him to get too full of himself. But, I’m not worried that that will happen. I hope that his strong form at Bayern will carry over to this tournament."
