MANCHESTER UNITED new boy Leny Yoro was seen using crutches and wearing a protective boot at the club’s Los Angeles training base this week.

The 18-year-old was forced off during United’s pre-season friendly against Arsenal on Saturday.

He appeared to suffer a non-contact ankle injury during the first half and limped off with assistance from a physio.

Erik ten Hag admitted he and his team were “especially careful” with Yoro in the build-up to the match as he had only completed a few training sessions.

While he remained hopeful the injury would not be serious at the time, the French defender has since been seen using crutches.

He was also spotted wearing a protective boot at United’s UCLA training base in California.

The Red Devils are understood to be assessing the extent of the issue.

Yoro joined Man Utd in a £52million transfer from Lille earlier this month.
