Chelsea signing Robert Sanchez has taken a swipe at his former Brighton manager Roberto de Zerbi.

Sanchez says his new boss Mauricio Pochettino is on another level to his previous coaches.

“Really excited," he told the club website about working with Pochettino.

“I've missed the opportunity to work with a coach of that level. Obviously, [you can] watch him on his past clubs what he's done.

“What he brings to the club, the family ambience around the players is really good. His play style is something I suit really well. I'm going to contribute to win trophies at the club with him."

Sanchez also paid tribute to Brighton.

“I started my career in England with Brighton, they provided me with everything as a goalkeeper, inside and outside the pitch, to get much more potential out of me," he continued.

“Obviously I'm really happy and thankful, and now it's a bigger challenge."
