Former West Ham United goalkeeper Shaka Hislop is full of praise for Chelsea's new recruit Kepa Arrizabalaga.
The player arrived as a record transfer from Athletic Bilbao, with the English side having to pay his buyout clause.
Hislop is impressed with what he has seen from Kepa so far, with the player having started all his side's Premier League games.
He told ESPN: "What I've seen of Kepa in a Chelsea shirt, as with Athletic Bilbao, an incredible shot-stopper.
"I can't think of many, well I can only think of four more, better than him in the league.
"I think that's an outstanding acquisition by Chelsea. Watch that space, he may move up."
