Chelsea manager Mauricio Pochettino has explained his goalkeeping selection for their upcoming Carabao Cup clash.

The Blues take on AFC Wimbledon in the second round of England's secondary cup competition on Wednesday.

Pochettino was asked if second choice goalkeeper and recent signing Djordje Petrovic would start in the game.

He told reporters: “I am going to play [first choice Robert] Sanchez, I can confirm that because we still have not had the confirmation if Petrovic is available or not.

“We need confirmation [over the work permit]. We don't know if we can use him tomorrow, that is why we prepared for the game with Robert. But I think he (Petrovic) needs more time to understand the way we want to play, the concept with Tony [Jiminez] and Hilario.

“He is working well but we do not want to rush. We don;t know if he is going to be on the bench because the permit is still not around."
