Former Manchester United boss Jose Mourinho thinks Marcus Rashford must continue to score goals in order to replace Romelu Lukaku.
Belgium international Lukaku was sold to Inter Milan last week after Ole Gunnar Solskjaer allocated the starting forward spot to Rashford.
He didn't disappoint in Sunday's 4-0 win over Chelsea bagging two goals, and Mourinho wants to see Rashford continue that form throughout this season.
"He has to score more goals," Mourinho said on Sky Sports.
"Especially without Lukaku in the team it will probably be these two [Rashford and Anthony Martial], plus Alexis [Sanchez] and Mason [Greenwood]. He will be on the pitch all the time and he has the qualities to be better and better and better.
"He has the ambition and work ethic, he wants to improve, he wants to work. This season he has a big opportunity to be a better player and score more goals.
"It depends on the way they play. Playing the way they played today against a Chelsea team that allowed them to play the way they like to play, he is very dangerous. Against teams with compact blocks, a lower block, that are more physical, I think it is a bit more difficult for them."
