Manchester United winger Alejandro Garnacho is injured and will be out for several weeks

Alejandro Garnacho of Manchester United will be out for several weeks after suffering an injury in Sunday’s 0-0 draw with Southampton.

The 18-year-old entered the game after 73 minutes and appeared to be in pain after a challenge by Kyle Walker-Peters.

Garnacho was then substituted for Fred in the closing stages before leaving Old Trafford on crutches.

“It’s difficult to put into words how I feel right now,” Garnacho said.

“Unfortunately, I will be unable to assist my team and teammates in the upcoming games in what is a crucial part of the season for us at Manchester United.”

On Thursday, United will play Real Betis in the second leg of their last-16 Europa League tie before facing Fulham in an FA Cup quarter-final before the international break.

Garnacho had been called up by Argentina for friendlies earlier this month, where he could have made his international debut.

“I am also disappointed to have missed the opportunity to be with my Argentinian national team teammates in what would have been a great and proud moment for me and my family,” Garnacho wrote on Instagram.

“This is a part of football and our profession, but I’m already concentrating on my recovery.”

Walker-Peters received racist abuse online following the game at United.

In response to a comment about Garnacho, the full-back was called a racist term.

In a post on Instagram, Walker-Peters said “the racial abuse I received is something that no player or person should ever have to experience”.

“It would never be my intention to injure a fellow professional,” he said of Garnacho, adding, “I wish you a speedy recovery and hope to see you back in action as soon as possible.”
