Manchester United manager Erik ten Hag has said that he expects teenage star Alejandro Garnacho to be back on the pitch before the end of the season.

Garnacho, who has become a first-team regular in recent months, was forced off in the final stages of Sunday’s 0-0 draw with Southampton after earlier coming on as a substitute himself.

With the injury the result of an impact in a tackle, the young Argentine was later seen leaving Old Trafford wearing a protective boot and walking with crutches.

“It will take weeks, it is a serious injury. Once again, after Christian Eriksen, we have a serious injury after a contact,” Ten Hag said on Wednesday evening.

“It is difficult to make a diagnosis quickly. I saw him limping and that is why I took him off.

“He will be back before the end of the season. We need to get him back as soon as possible and we hope he is ready.”

Garnacho revealed his disappointment at having to miss upcoming United games and pull out of the Argentina squad for this month’s home friendlies against Panama and Curacao, which could have seen him make his senior international debut.

“It is difficult to put into words how I’m feeling right now,” he posted on Instagram on Tuesday.

“Unfortunately I will not be able to help my team and team mates in the upcoming games in what is a very important part of the season for us at Manchester United.

“I am disappointed to also miss the opportunity to be with my team mates of the Argentinian National Team in what would have been a great and proud moment for me and my family.

“This is part of football and our profession, however, I am already focused in my recovery. God has taught me to never give up and I will make sure I am back stronger than ever!”
