Reds' manager bemoaned United's first half display in their win over Hull.
Manchester United made it nine wins in a row, beating Hull City 2-0 in the EFL Cup semi final first-leg at Old Trafford. The Red Devils broke the deadlock in the 60th minute with a close-range strike by Juan Mata and substitute Marouane Fellaini doubled the lead with a fine header in the 87th minute as Mourinho's Reds head into the second leg at the KCOM stadium with an advantage.

"But I think we were a bit sloppy, complicating things, always one more touch, delaying the decision, giving them time to regroup and it was not our best first half.

"Second half we all improve just a little bit. The game is over, now I think about Sunday and on Sunday I have to do better, the players need to do better and the stadium has to do better."
Mourinho felt his side shouldn't have celebrated after Mata scored the first goal with 30 minutes left to play.
"We needed to play," he said. "In cup ties every goal can be crucial so why celebrate when you have half an hour to play?
"I don't think we should, there is no reason to celebrate the first goal."
