Manchester United boss Jose Mourinho has again questioned his players' commitment after their 0-0 draw with Crystal Palace.

Mourinho questioned his players' "heart" at the final whistle.

He said, "You can influence players, especially when they are open to it. When a player is open to it and a player realises he must give more and has to change his nature a little bit and is open, they change.

"There are many examples showing that coaches and managers can change a little bit in their players, not their DNA but their emotional qualities. I am what I am, every individual is different. There are people who will have a bad dinner, there are people who enjoy a nice dinner and there will be people that may party. I think that is the way it is."
