“I don’t worry about that, he’s getting the chances,” the United boss said. “Of course he could have scored three [against Astana], but the goalkeeper made a few fantastic saves.
“We’re working every single day in training with Marcus and he wants to improve and he wants to be better. He could have finished with his left foot instead of his right once, but it was just one of those days.
“All the goals we’ve scored have come from our forwards with Marcus, Anthony [Martial] and Dan James so I’m sure he’ll chip in with many, many goals.

“He’s still young, he’ll improve and you won’t hit your peak as a striker until you’re 26 or 27. He’s still learning what finishes to make in different circumstances.
“I think today’s forwards are different from the old, traditional number nines. There’s not many left of them and Marcus can play three or four positions.”
‘Last season we were lucky to beat West Ham’
United return to Premier League action on Sunday when they take on West Ham at the London Stadium, live on Sky Sports Premier League.

He said: “By the quality and by the game we played against them last season and the games I’ve seen them this year, why not?
“Last year we were lucky to beat them and it’ll be a good test again for us. We’ve had two clean sheets now, that gives the defenders confidence and if we can keep a clean sheet then it will be easier for the strikers because you know that you don’t have to score twos, threes and fours every time.”
United have not won an away match in all competitions since March – when they beat Paris Saint-Germain in the Champions League – but Solskjaer insists he is not worried about their struggles on the road.
