The 18-year-old scored twice in the second half to become the youngest Manchester United player to score a brace for the club in a major European competition at the age of 18 years and 72 days.
The Englishman is now the Red Devils’ top scorer in Europe this season with 5 goals, and only Marcus Rashford has scored more goals (13) than him in all competitions for Manchester United so far.
Solskjaer insists he is not surprised about the youngster’s quality, as it has been on show in training every day.
“I’ve probably said it all before. It’s nothing new - that’s what he does and tomorrow he will probably go into training and score a few more,” the Norwegian tactician said.
"He has always done it. That is just natural for him. He is a natural footballer.”
"The closer he gets to goal the more dangerous he is. Right foot, left foot, he is a nightmare for defenders.”
"He needs to develop his heading. Then he can be a proper striker.”
Greenwood’s instinctive finishes has forced Solskjaer to compare him to Manchester United’s all-time scorer Wayne Rooney, who was very prolific during his time at Old Trafford.
He added: “I’ve seen a few good ones – I played with Wazza [Wayne Rooney]. But for natural finishing he’s one of the best I’ve seen.”
"He’s a different class as a finisher - in and around box you expect him to get a shot off and on target. He is so precise with his finishing.”
"Mason must have enjoyed tonight. He’s just going to look forward to Sunday now, but he won’t rest on laurels."
