Interim Manchester United boss Ralf Rangnick considers the Anthony Martial matter "resolved" after speaking to the France forward.
Rangnick had said Martial "didn't want to be in the squad" for Saturday's game against Aston Villa.
Martial, 26, responded on Instagram by saying he "will never refuse to play a match for Man United".
"I had a conversation with him on Sunday," said Rangnick on Tuesday. "The matter is now resolved."
United had two goalkeepers among their eight substitutes - which is one short of the number allowed - for the 2-2 draw at Villa Park.
