Manchester United received an injury blow as midfielder Scott McTominay was forced off with an apparent stomach problem against Arsenal on Saturday evening.
McTominay was replaced just before half-time clutching his midriff, although he appeared to be struggling with the issue earlier in the match.
Twenty minutes in Arsenal midfielder Thomas Partey glided past him and he was clearly off the pace and unable to keep up.
The Scotland international had taken a pill to try to settle his stomach earlier in the match but it was clearly unsuccessful.
