Frank Lampard has vowed to back goalkeeper Kepa Arrizabalaga despite another mistake from the Spaniard in Sunday's 2-0 loss to Liverpool.

A sloppy pass from the 25-year-old was intercepted by Sadio Mane, who swiftly made it 2-0 to the visitors.

It followed on from a mistake in last Monday's win over Brighton, but Lampard insists he's sticking by his shot-stopper.

"I can say now that Willy Caballero will play and that was always my feeling that he will play in that game even before today," he told reporters.

"He [Kepa] is our player and it is clear now that there are two games where we have felt [he has made a mistake]. Today was a clear mistake and Brighton was a mistake too and he has reflected on it in that way.

"We have to keep working, it is the rule of football. Players need support, particularly from myself. I give that to all the players.

"Kepa has to keep working, nobody tries to make mistakes in football, it is the nature of the game. You have to be strong, you keep going and that is where he is at."
