Manchester United striker Mason Greenwood’s form has made it impossible to leave the teenager out of the starting line-up, manager Ole Gunnar Solskjaer has said.

Greenwood scored his 16th goal in all competitions for United this season in their 3-0 victory over Aston Villa on Thursday.

“You cannot leave players out when they score goals,” Solskjaer said. “He’s 18 and of course he will get better.”

United went ahead in the 27th minute after a debatable penalty award when referee Jon Moss ruled that Ezri Konsa had brought down Bruno Fernandes just inside the box. There was no dispute about United’s second goal, though — a thundering drive from Greenwood. Paul Pogba wrapped up the win.
