Luke Shaw left the Emirates Stadium on crutches in a protective boot after suffering a new ankle injury.
The 19-year-old twisted his ankle early in the first half after making a clearance and although he tried to play on, he was substituted soon after.
It’s a cruel blow for Shaw who has had to contend with multiple injury setbacks this season and this could mean Shaw is set for another period on the sidelines.
Shaw will likely undergo a scan this evening to assess the extent of his injury and Louis van Gaal will be hoping that it is nothing serious.
Ashley Young came on and played as a left wing-back in his place and to his credit, Young played very well and certainly helped United secure the three points in what was a gritty 1-2 win.
