The Manchester United winger was taken off for Noussair Mazraoui following Patrick Dorgu’s red card for a reckless challenge on Omari Hutchinson.
With United down to 10 men and leading 2-1, Ruben Amorim opted for defensive reinforcement, sacrificing Garnacho’s attacking threat.
Fan footage from the stadium revealed that Garnacho informed staff he was heading to change his shirt—an off-camera moment not shown on TV.
Supporters inside Old Trafford booed Amorim’s decision, as the Argentine had shone on the left flank during the first half.
The 20-year-old played a key role in United’s counter-attacks after Ipswich’s early opener, exploiting space in transition.
