Henrikh Mkhitaryan was making his his first-team comeback in the Europa League defeat at Fenerbahce.
The playmaker, signed from Borussia Dortmund in July, made his first United outing since the Manchester derby on September 10 when he replaced Marcus Rashford in the 61st minute of his side’s 2-1 loss in Turkey.
But despite the fact United were two goals down by the time Mkhitaryan made his entrance, Mourinho singled out his performance for criticism and demanded better if he is ever going to become a regular, even though he does not currently plan to sell the 27-year-old.
“I’m not thinking about sending him off, but he has to do more – it’s as simple as that,” Mourinho said in his post-match media conference.
