“We don’t score enough goals, it is as simple as that.
“The pragmatism is – how many goals have (Marcus) Rashford, (Jesse) Lingard, (Henrikh) Mkhitaryan, (Ander) Herrera, (Paul) Pogba scored? How many goals from these attacking players? Not enough.”
Mourinho said Shaw had produced a “very positive performance”, but also claimed he had been “making every decision” for the left-back.
“He had a good performance but it was his body with my brain,” Mourinho said.
“Because he was in front of me and I was making every decision for him.
“We need at this level the fantastic body he has to play football, the fantastic physical qualities he has, the very good technical ability he has – but he cannot play with my understanding of the game.
“He must understand the game, he must think and he must accelerate the process.
“Twenty-one years old is old enough to have a better understanding of the game – but his contribution was good.
“He goes today in a positive feeling because his performance was very positive. I’m happy with what he gave us.”
