Chelsea boss Pochettino struggles to deliver Nkunku update

Chelsea manager Mauricio Pochettino was reluctant to elaborate on the fitness of Christopher Nkunku.

The French international has been absent for most of the season with various injuries.

Pochettino was asked during a pre-game press conference whether he had suffered a setback in his recovery.

On a time scale, he told reporters: "I don't know. Still we don't know."

On whether there had been a setback, he added: "To return to training? I don't know what I said. At the moment we do not know when it is possible to start to train with the team. At the moment he is not training with us.

"That setback didn't happen. I have no information about that. He is recovering and it has been longer than we expected. That was after the final, he played 30 or 40 minutes. The problem we didn't know and we found after the game.

"This type of circumstance, it affects loads of things, too many players have suffered this season. I hope he can be involved again as soon as possible in the dynamic of the team and of course, if he should be really, really good before the end of the season, I hope he can be part of the team."
