“He has come back after the lockdown with a smile on his face and loads of energy,” Solskjaer said of the player with a year left on his contract.
“Last week he fell ill for a couple of days but we have done all the tests and he’s fine.
“He will be involved against Norwich now.
“Hopefully he can kick on. He has scored vital goals for us, and has been a vital player for us.
“Let’s see what the future will hold.
“At the moment he is looking really sharp and focused.”
Lingard has not started in the league in 2020 as he has fallen down the pecking order due to his lack of form and the introduction of Bruno Fernandes.
The United manager also talked of his time in as a player involved in the FA Cup.
“The FA Cup is fantastic,” Solskjaer explained. “When you are a young boy back home it was always the last game, the climax of the season, the game you looked forward to, the one that was broadcast live in telly in Norway.
“That goal against was probably my best moment in the FA Cup apart from climbing steps at the old Wembley to get my medal. I played [a part] in the first goal in the ’99 final, winning the ball.
“That was a proud moment for me. My dad was in the stands.
“I have lifted it twice as a player. Hopefully I can get a chance to walk out again at Wembley.
“It’s a fantastic tournament, it’s always been the big one. I am not sure youngsters nowadays really understand what how much it means but our players realise.”
