Can partnered Reds captain Jordan Henderson in the midfield as the Reds gained a commanding lead from the first leg of their last-16 meeting with United.
The German has been praised for his recent form, including his display against Louis van Gaal's side, but despite him feeling he's playing some good football, Can feels there were one or two errors in his game.
He's quoted in the Liverpool Echo, saying: “I made a few mistakes.
“I have to play better but I feel like I'm developing as a player under Jurgen Klopp.
“I know the boss is behind me. I want to improve every day and I always give my best for the team.”
The 22-year-old was used as part of a back three under Brendan Rodgers but ever since the appointment of Jurgen Klopp, he has been used regularly at the heart of the Liverpool midfield. Sometimes he has been used further forward but in recent weeks he seems to have flourished in the holding role.
The fact he has a manager that communicates in the same language as him has perhaps aided his development, and it is clear that Klopp trusts Can during the process he has tried to implement his style on the team.
There have been times when he has been caught wanting but there have been one or two aspects to his game that have markedly improved, including his use of the ball and the fact he offers a big presence in the middle of the park - meaning he can use his body to good effect to break up the play.
Given that he feels there is room for improvement shows there is a real desire for him to keep on learning, and since he is only 22, there could be another couple of levels for his game to reach.
