Arsenal's new signing Mikel Merino is set to be out for several weeks after suffering a fractured shoulder in his first training session.

The midfielder, who joined from Real Sociedad in a £31.6million deal earlier this week, sustained the injury in a clash with Gabriel Magalhaes.

Merino had been expected to make his debut for the Gunners against Brighton on Saturday, but Mikel Arteta confirmed that would not be possible.

"Very unfortunate," Arteta told a news conference. "On Thursday, he had a collision, and he has a shoulder injury, unfortunately.

"It looks like he's going to be out for a few weeks. First session. He was really excited, and everything was looking really good.

"He landed on the floor and Gabi landed on top of him, and it looks like he has a small fracture, probably.

"We have to see [how long he is out for]. He was in so much pain. We'll have to do some more tests on that and then we'll have more conclusive answers."

Arsenal have also announced the signing of Neto on a season-long loan deal from Bournemouth following Aaron Ramsdale's departure to Southampton.

The goalkeeper started the Cherries' first two Premier League games of the season, making 11 saves and conceding just twice.

In 63 appearances for Bournemouth in all competitions, he kept 13 clean sheets and helped them to a 12th-place finish in the top-flight last season.

Arsenal have announced the signing of Mikel Merino from Real Sociedad on a four-year contract.

The midfielder has joined in a deal worth up to £31.6million, with the option to extend his stay for an extra year.

Merino is returning to the Premier League, having signed for La Real from Newcastle United in 2018.

He made 242 appearances for the Spanish side in all competitions, scoring 27 goals and registering 30 assists.

Last season, he won 326 duels, the most of any player in the top five European Leagues, while his 197 recoveries in LaLiga were the most of any outfield player for La Real.

"Mikel is a player who will bring us huge quality with his experience and versatility," Mikel Arteta said of his new signing.

"He has played at the top of the game at both club and international level for a number of seasons now. Mikel will make our squad significantly stronger, with his technical ability, together with his strong and positive character and personality.

"As we all saw in the summer, Mikel is also a winner, with his strong performances throughout the Euros helping Spain win the tournament. We are delighted to welcome Mikel and his family to the club and can't wait to start working with him."

Merino is the fourth signing by Arsenal during this transfer window, after Tommy Setford, Riccardo Calafiori, and the permanent move for David Raya.

Real Sociedad president Jokin Aperribay has revealed the club will talk to Arsenal over a potential transfer for Mikel Merino, admitting the midfielder has a price.

Merino was left out of La Real's squad for their opening match of the season in LaLiga on Sunday, a 2-1 defeat at home to Rayo Vallecano.

The 28-year-old, who was part of the Spain team that won Euro 2024 last month, has made 242 appearances for La Real since joining from Newcastle United in 2018.

Reports have suggested Arsenal are working to bring him back to the Premier League in the closing days of the transfer window, with a fee of around £29.8million mooted after Merino entered the final 12 months of his contract in San Sebastian.

Aperribay has now revealed La Real are open to a sale for the right price after Merino indicated he was unwilling to renew his deal with the club.

"Merino was clear that he didn't want to say he was renewing and then leave. It wasn't a surprise to us," Aperribay told Basque Country radio station Onda Vasca.

"Unfortunately, one of the teams we didn't want to show up showed up. We will talk to Arsenal and defend the interests of La Real.

"When we consider that the offer is good, we will say yes. We know what Merino's wishes are, so we decided that he should not be called up [on Sunday]."

Spain have confirmed that Pedri will miss the rest of Euro 2024 after suffering a 'grade two knee sprain' in Friday's quarter-final victory over Germany.

Pedri had to be substituted after just eight minutes in the clash in Stuttgart following a heavy tackle from Toni Kroos.

Spain won 2-1 after extra-time thanks to Mikel Merino's late strike and will face France in the semi-finals in Munich next Tuesday. 

In a statement post on X, it read: "The medical tests carried out have determined that Pedri González suffers a grade 2 internal lateral sprain in his left knee.

"The Canarian player will remain in Germany until the end of Euro 2024."

Kroos, who called time on his football career following Germany's defeat, sent his best wishes to the Barcelona midfielder in an emotional farewell post. 

"Get better soon Pedri. Obviously, it was not my intention to cause any damage," Kroos posted on Instagram.

"Wishing you a speedy recovery and all the best. You are a great player."

Luis de la Fuente hailed his Spain side as an "example for the country" after their last-gasp win over hosts Germany in the Euro 2024 quarter-final.

La Roja came out on top with a 2-1 victory in Stuttgart thanks to Mikel Merino's 119th-minute winner in extra time on Friday.

Dani Olmo had given Spain the lead in the second half, and looked to have scored the match-winner until Florian Wirtz equalised at the end of normal time.

After their last-gasp win, De la Fuente was full of praise for the fighting spirit his side showed to get the result.

"I'm proud of this group of players, such a committed group of players, who are an example for our country, for our society, and for any sportsmen and women who want to be competitive and want to improve every day in order to try and be a bit better every day," De la Fuente said.

"Our team has heart, and I know them; they have ambition, and they are eager to be better every day. They never tire of improving, and I am proud to coach them."

Spain and Germany had perhaps been the tournament's standout performers in the first four rounds of matches, and the match lived up to its billing.

De la Fuente's side have now won all five of their matches at Euro 2024 and will play France for a place in the final on Tuesday.

"We will see how far we can get, but I'm really proud of the example that this team is giving out in terms of companionship and values and so on, and this is what I value the most, apart from the quality of my players," he added.

"We are happy, but we know that tomorrow is a different day, and tomorrow it's another game already. So yes, we are happy, but the euphoria is very much under control."

Unai Simon acknowledged Spain would have to recover their focus amid celebrations of a quarter-final win over Germany that felt "like a Euros final".

La Roja are still two victories from the Euro 2024 title, but they have cleared their greatest hurdle yet after beating the hosts 2-1 late in extra time on Friday.

Subsitute Mikel Merino headed a 119th-minute winner, with Spain earlier frustrated by a Florian Wirtz equaliser at the end of normal time.

Goalkeeper Simon was in no mood to talk down his side's achievement, even if attention must soon turn to Tuesday's semi-final.

"What we have achieved is historic, winning this game is like a Euros final," he said.

"We have already celebrated, but we have to recover because in four days we have a semi-final."

Spain and Germany had perhaps been the tournament's two standout teams through the first four rounds of matches, and this meeting did not disappoint.

"It was the match we were all waiting for, between two of the best teams in the world," said Merino.

"It could be a World Cup final or a European Championship final; the level of those who have come off the bench is very high.

"We have shown that we know how to suffer, that we have a great team."

Spain suffered physically as well as mentally in a feisty encounter that saw 15 cards – the second-most in a Euros match – even if they gave as good as they got.

Robin Le Normand's second yellow card of the finals will now see him miss the next round, with Dani Carvajal also banned. He was already set to sit out the semi-final even before a last-gasp second booking – and third of the tournament – saw him sent off.

Alvaro Morata also appeared to be suspended for a card from the bench in the aftermath of Merino's goal, but the caution was later removed by UEFA.

Regardless, Spain coach Luis de la Fuente is backing the players on the fringes of his squad to deputise in the same effective fashion as super sub Merino.

"Any of the 26 players are ready," he said. "Each one has his role at the right time.

"I am very proud of these players. Tomorrow we will recover, and we will try to have as many players as possible."

De la Fuente might also be without Pedri through injury following a foul from Toni Kroos that was not punished with a card.

The Barcelona midfielder was wiped out in the opening minute of the match and soon had to be replaced by Dani Olmo, who himself stepped up with the opening goal and an assist for Merino.

"Pedri was in pain," De la Fuerte said. "I think it was a red card [for Kroos].

"Whether Pedri is on the pitch or off [for the rest of the tournament], he's going to keep contributing."

However, the coach added of Germany's rugged approach: "These are games like that, when you're playing for so much, at this stage, you have to use all your weapons. I have no complaints about German football."

Mikel Merino's last-gasp header sent Spain into the semi-finals of Euro 2024 as La Roja beat hosts Germany 2-1 after extra time.

Florian Wirtz's 89th-minute strike had cancelled out Dani Olmo's calm finish in a frantic encounter in Stuttgart on Friday.

Yet having had the best chances of extra time, Germany became the first Euros hosts to lose a quarter-final when Merino brilliantly headed home Spain's latest ever goal in the competition in the 119th minute.

Niclas Fullkrug's header was just inches away from rescuing Germany and setting up penalties, but Luis de la Fuente's team, who had Dani Carvajal sent off late on, held on to tee up a clash with either Portugal or France.

Pedri's early injury saw Olmo come on, and the substitute sparked a slow-burner of a contest into life in the 51st minute.

After seeing Alvaro Morata lash over from close range, Olmo made no mistake when he side-footed home from Lamine Yamal's cutback.

Simon made a fantastic save from Robert Andrich's drive, before the post came to Spain's salvation when Niclas Fullkrug's effort clipped off the right-hand upright.

Germany should have been level when Simon made a calamitous clearance soon after, but with the goal at his mercy, Havertz chipped over.

But Havertz's blushes were spared by Wirtz, who drilled in off the post after latching onto Joshua Kimmich's knockdown.

Wirtz had the best chance of the first half of extra time, sending a low effort just wide, before chaos broke out.

Germany saw a penalty appeal turned down after Jamal Musiala hit Marc Cucurella's arm, and Simon saved a fantastic Fullkrug header.

With penalties beckoning, Spain broke clear, and La Roja were in ecstasy as Merino planted in from Olmo's inch-perfect cross.

Ferran Torres' poor finish moments later could have proved costly had Fullkrug's attempt been half a yard to the left, but it was not to be for Germany, even though Spain were reduced to 10 for the final minute after Carvajal picked up his second booking.

Spain call on the super-subs as Lamal sparkles again

Olmo is now the first Spain player to score two goals as a substitute at a single edition of the Euros, and third at any major tournament, after Fernando Morientes at the 2002 World Cup and Morata at the 2022 edition of that competition.

The RB Leipzig attacker is also the second player to have scored in two consecutive knockout stage appearances for Spain at the European Championships, after Chus Pereda way back in 1964.

And Merino's winner meant Spain have now scored two goals from substitutes in a single Euros match for just the second time, after the Euro 2012 final against Italy.

There has been no such scoring luck so far for Yamal at Euro 2024, with the youngster having had 13 shots without finding the back of the net (only Cristiano Ronaldo, with 20, has had more attempts and not scored at this tournament).

However, he again showcased his creative talents, laying on three chances and taking his tally of assists for the tournament to three. He is the first-ever teenager to record three assists at a single edition of the Euros or World Cup.

Musiala cannot find the magic touch

Jamal Musiala went into Friday's tie having scored in three of Germany's four previous games, and aiming to move clear at the top of the Euro 2024 scoring charts and match Wayne Rooney (at Euro 2004) as the only player to score four goals at a single edition of the tournament while aged 21 or younger.

Yet the Bayern Munich playmaker struggled to wield his usual influence on proceedings, creating only one chance, and though his fellow youngster Wirtz shined, it was not enough for the hosts.

There will be more major tournament opportunities for Musiala and Wirtz, but at the other end of the age spectrum, Toni Kroos made his final appearance before retirement. The 34-year-old finished the match with 83 passes attempted, the most on the pitch.
