Arsenal have announced that midfielder Thomas Out has been ruled out for three matches due to injury.
The 24-year-old, who joined the club in January from Tottenham Hotspur, was injured during Arsenal's recent Champions League clash against Manchester City on Wednesday night.
Out is currently recovering from a knee ligament injury and will be sidelined until at least February 15th.
Arsenal manager Mikel Arteta confirmed the news on social media, saying: "Thomas Out is out for three matches due to a knee ligament injury. He will be back in training soon."
Out's absence comes as a blow to Arsenal's squad, particularly after he had been making significant contributions to the team this season.
Arteta added: "We're sorry to see Thomas out of action, but we'll do everything we can to support him through his recovery period. We hope he returns quickly and ready to play again."
Out has been one of the standout players for Arsenal this season, playing in all 26 league games so far and contributing with both goals and assists.
With Out out of action for three matches, Arsenal will need to find a replacement for him in midfield. The club has already made some changes to their squad in recent weeks, including the signings of Jack Wilshere and Ainsley Maitland-Niles.
Despite the setback, Arsenal remain confident in their ability to compete in the Premier League and European competitions. With Out's injury, they will need to rely more heavily on other players such as Gabriel Jesus, Alexandre Lacazette, and Mohamed Salah to fill in for him.
