Manchester United boss Jose Mourinho admits he fluffed his selection for derby defeat to Manchester City.

Jesse Lingard and Henrikh Mkhitaryan were brought in to the line-up for the derby, but replaced at half-time after poor displays.

Mourinho took responsibility for mistakes in the team set-up and, despite insisting they were not the only poor performers, suggested the duo could have come off sooner.

"I didn't change after 20 minutes because I don't want to destroy the players," he said.

"I didn't want to make three changes at half-time because I was afraid in long 45 minutes something happened.

"If it was a sport with a free number of changes and where the changes during the first half is something normal like basketball and all this kind of stuff, I would do after 20 minutes.

"But I did at half-time, we changed the direction of the game but we didn't get the compensation I think we deserved in the second half."
