Alejandro Garnacho will buy dinner for the Manchester United squad as an informal punishment for storming down the tunnelwhen he was substituted in Wednesday’s win over Ipswich.

Manager Ruben Amorim said the 20-year-old needed to understand that perception matters at a club the size of United and that it was a bad look when he did not return to the dugout or reappear with other squad members for the second half.

But he revealed that the winger was quick to come an offer an explanation for his behaviour on Thursday morning and his own research showed that Garnacho had not left Old Trafford.

The Argentina winger was taken off in the first half, when Amorim said he was playing well, in a reshuffle caused by Patrick Dorgu’s red card and he demonstrated his disappointment with his manager’s decision.

Amorim said: “It was funny because the next day he came to my office. I did some investigations, he went to the dressing room to change his clothes because he was wet. He watched the game, not in the bench, and at the end of the game he was there and went home. So it is not an issue. But at a big club like Manchester United everything is important and perception is important. He is going to pay a dinner to all the team and that is it.”
