Manchester United boss Erik ten Hag was delighted seeing Mason Mount score in Saturday's 1-1 draw at Brentford.
It marked Mount's first goal for the club.
He will face form club Chelsea tomorrow and Ten Hag said: "He's a fantastic football player but it's important first that he is getting and keeping fit because he has had three injuries.
"We have to do this carefully. The first objective is to keep him fit.
"Then he can benefit and contribute to the team like he did on Saturday when he had a big impact [scoring against Brentford]."
