The Armenian midfielder made his Premier League debut after many believed he would be left sidelined with a thigh injury that he picked up while on international duty.
Lingard was a surprise inclusion in the starting XI, but after performing in some of Man United’s bigger games, the Portuguese boss would have been aware of his ability.
Speaking about the derby, Mourinho claimed the pair could bring his side something different.
“I have the feeling Jesse and Mkhi can bring us something different today,” he said.
“The structure of our team is basically the same, Mata, Martial, Young, Memphis, we have lots of solutions in these two positions.”
The pair had been so poor throughout the game fans were urging the Portuguese boss to substitute them off throughout the first-half.
Lingard looked completely out of the game, he was often dispossessed on the flank and was very sloppy with his balls, while Mkhitaryan seemed unready to return to action so quickly after enduring an injury.
After a recent dip in form, time on the bench will not act as a punishment, but as a reminder that Anthony Martial needs to start performing to keep his vital place on the side.
