Manchester United boss Erik ten Hag admits he needs more from Marcus Rashford.
Rashford was hooked for Alejandro Garnacho during defeat at home to Crystal Palace on Saturday.
Ten Hag said: "I think he knows he can do better than he is now and I'm sure it will come.
"He works hard and it will come, but not automatically. The team has to work around him, and they have to invest a lot. The decision-making wasn't good enough and then we don't score."
He also said: ''I can't blame the players that they didn't run, I think they gave everything. In the final part, in both boxes, we didn't do well. We only conceded three chances and the three chances were all from set plays. That tells me we were in control.
"We were often in the final position in the final part, but as I just explained we didn't make the right decisions, on and off the ball; that is of course very disappointing. We have to be more clinical and be more determined. So if you asked me that question, we have to be more clinical and determined to score a goal. You have to show more willingness to get more impact if you want to score a goal.''
