Chelsea boss Frank Lampard is willing to give Willy Caballero a chance to be his first-choice goalkeeper.

Caballero will replace under-fire Kepa Arrizabalaga for Chelsea's fourth round tie against Hull City and Lampard insisted he will have a chance of retaining his starting position if he plays well.

"All the players that play do," Lampard said.

"All the ones who don't start regularly. Those are the rules."

Lampard added: "That's where the goalkeeper I suppose is a specific position.

"Where it's quite well known there's a number one and a number two. But my choice is to make that choice after the game considering the next game."
