Manchester United boss Ole Gunnar Solskjaer felt Mason Greenwood improved Manchester United’s ball retention in the 2-2 Champions League draw with Atalanta on Tuesday night.

Greenwood replaced the injured Raphael Varane in the 38th minute as Solskjaer opted to switch to a 4-2-3-1 after starting the game with 3-5-2 system.

Solskjaer said after the 2-2 draw against Atalanta: “I felt first-half, we didn’t get the openings, you know their man-marking system and our rhythm and the quality of the passing wasn’t great, wasn’t good enough. We gave them too many turnovers, too many transitions.

“Mason, apart from Cristiano and David, Mason has had a very, very good season and is so clean on the ball and he keeps holds of it, if he gets man-marked one against one, he’ll keep it.

“And we were 1-0 down and you still have to have the discipline and make sure we don’t go gung-ho open, but and we needed a little bit more up front and Mason provided that quality.”

Varane sustained a hamstring injury against Atalanta and is a doubt for the Manchester derby at Old Trafford on Saturday.
