Chelsea boss Frank Lampard urged to snub £100m transfer because of 'underrated' star

“People talk about the goalkeeper being a priority,” Merson, a self-confessed Chelsea fan despite his history with Arsenal, said to Sky Sports.

“Kepa Arrizabalaga is not saving them any points at the moment, that’s a problem.

“But they have a really good second goalkeeper in Willy Caballero, and I think he is really underrated.

“In this day and age, if we’re talking about Jan Oblak, he’s going to cost £100m. Kepa himself cost £71m, and has big wages too.

“I’m not sure about this one, as it wouldn’t be my major priority for the summer for Chelsea.

“Do they sign another £100m on a goalkeeper, where you’ve already got a goalkeeper you’ve spent £71m on, on big money, and you’re not going to get that money back?
