Mauricio Pochettino has admitted that Chelsea will miss Robert Sanchez when they take on Sheffield United on Saturday.

Sanchez has been Chelsea’s number one goalie since he joined from Brighton in the summer.

The 26-year-old is however not available to play against Chris Wilder’s side after suffering a knee problem in the 2-0 loss to Everton on Sunday.

Asked about the absence of the Spaniard, Pochettino told reporters on Friday: “I think always when you suffer an injury and he was our No.1 goalkeeper so far, always a player we will miss. We have another goalkeeper who is working hard to be ready. Of course, very sad because we are going to lose a player, maybe for a few weeks. We need to wait and see perfectly the situation and also with Reece and Marc Cucurella.

“From the beginning we are being hit with different circumstances. We need to be strong because the competition doesn’t stop.”

On Petrovic, Poch added: “Of course. I have faith in all of my players. He arrived at Chelsea because we believed he had great potential. Now after four or five months working with us is the moment for him to step up and feel good because we have the trust in him. Now is to make the debut in Stamford Bridge, yes we trust that he can perform in the way we want.”
