Jurgen Klopp is unfazed by interest Barcelona has in Philippe Coutinho.

Coutinho signed a new five-year deal with Liverpool in January.

Liverpool have reportedly told Barcelona that Coutinho won't be for sale this summer.

"Actually, I think it's positive when there is interest," Klopp said. "It shows it's good. I am not concerned because I think Phil fits really well and comfortably here.

"He had a difficult time with injury, coming back fighting for shape, I would say. That's normal. In the last three games, you can see immediately, when he is in a little bit of shape, how big the difference is he can have in a game.

"That's wonderful for us. I am not concerned, actually, because we give the boys enough perspective that they really want to be part of this for the next few years."
