Ole Gunnar Solskjaer says Paul Pogba remains committed to Manchester United after missing the club's final pre-season game and Harry Maguire could play in next weekend's game if his transfer is complete.
Asked whether he was concerned about Pogba's commitment to United, Solskjaer replied: "I've no doubts at all.
"I wasn't expecting him (on the plane).
I spoke to him after training and he didn't feel right.
"Paul will probably be back early next week training.
It's not an injury, he just felt some pain.
We didn't want to risk anything this weekend and he should be OK for Chelsea.
I hope so." He made the comments during a press conference after his side beat AC Milan 5-4 on penalties, having drawn 2-2 in the International Champions Cup.
