Nemanja Matic says Manchester United should be winning games like the one against Crystal Palace on Wednesday.
The Red Devils failed to threaten Palace in a goalless stalemate at Selhurst Park.
"Palace played solid compact football," Matic said. "They waited for their chances. They had a opportunity to win the game at the end.
"We have to do much better, we have to risk more in attack to create more chances.
"We are Manchester United, we have to win this kind of game. On Sunday we have a big game against Manchester City. We have to refocus for that.
"When we don't win we are frustrated. The feeling in the dressing room wasn't great. If we need to take some positives, it's a clean sheet."
