Chelsea manager Frank Lampard has said the club's board back his decision to drop goalkeeper Kepa Arrizabalaga to the bench.

Kepa became the world's most goalkeeper when he moved to Chelsea for £71.5 million last season but he has struggled recently and been replaced by Willy Cabellero for last three matches.

Chelsea have conceded five goals in that time but Lampard said the board have no issues with his decision.

"I am absolutely together with the club and the board," he told a news conference. "We all want the best. I am paid to make decisions.

"It has been a decision to make on form with the goalkeeping situation. Recently it's just changed, but that's nothing final.

"All Kepa needs to do is train and show a great attitude, as I demand from all the players. And things can obviously change."

Lampard also confirmed that N'Golo Kante will miss the next three weeks after he sustained a muscle injury in the 2-0 loss against Manchester United.

The Chelsea boss said he has no return date for Christian Pulisic but Tammy Abraham and Ruben Loftus-Cheek will be back for the Tottenham game on Saturday.

The Blues have only won one of their last five Premier League matches and Lampard has challenged his players to get back to form.

"They have to rise to that challenge," he added. "If you want to play for Chelsea you have to."
