Chelsea head coach Thomas Tuchel is not concerned about Andreas Christensen's commitment to the cause at Stamford Bridge.

Centre-back Christensen was a crucial part of Chelsea's success under Tuchel last season.

However, the Denmark international is out of contract at the end of this season and so far no extension has been agreed.

According to reports, a move to Barcelona is already lined up, with Christensen thought to be one of the players Joan Laporta referred to when he confirmed that the Catalan giants had secured the signings of two out-of-contract players for next season.

Christensen last featured against Lille on March 16, having been left out for what Tuchel explained as tactical reasons on Saturday, when Chelsea were thrashed 4-1 by Brentford.

The 25-year-old's future was brought up in Tuchel's news conference ahead of Wednesday's Champions League quarter-final tie against Real Madrid, with the issue of a potential lack of commitment mooted.

"No. No concerns," Tuchel replied. "Maybe it is a bit more challenging for him than normal, in a moment where everything is clear or you're fully committed to the club you play for, which is us and Chelsea.

"Maybe he cleared his future, I don't know it yet, but for me it was very clear when I started, and the bottom line in conversations I had with him was that as long as you're my player I expect you to be 100 per cent committed and I will not accept anything less.

"I will not start digging into how committed is he now, this only leads to distraction. This is what I demand from him. That he was out on Saturday was only a tactical choice to play with a back four.

"He is our player and we want to have the most of him. He needs to be focused, he needs to be determined, and this is what we expect from him. And I think it is what we can expect from him."

Christensen has featured 26 times in all competitions for Chelsea this term, starting seven games out of the eight the Blues have played in the Champions League.

While it seems likely this season will be Christensen's last at Chelsea, Tuchel has no ill feelings towards him.

The German does, however, believe that Christensen should remember the opportunities he has had to develop at Chelsea.

"The situation of the club was pretty sure. I think I gave you an honest statement that he is in exactly the right place for his journey," Tuchel said.

"That he could continue with this club and become the defender that he can be, the real personality and the playing minutes figure that he wants to be.

"In my opinion, he shouldn't forget where he comes from, where his education comes from, where is home and that's just my opinion. He needs that kind of environment to bring the best out of him.

"That's just my opinion and I gave it some weeks ago but the talks in autumn and the summer were constant talks. We are in exchange with our players of course. I hope that my talks didn't make him want to leave but I don't think so.

"You cannot take these things personally. If he decides to take his career elsewhere, it is his decision. We understand it, maybe we don't need to agree. We will not take it personally.

"As long as he is our player, he is our player and I will not stop demanding from him. He needs to be fully, fully committed, this is what we expect and have experienced. You will have to ask him about his decision and what the reasons are."
