Chelsea boss Graham Potter has discussed how he tackled rebuilding the confidence of Kepa Arrizabalaga.

The Spain international started Tuchel's last match – a 1-0 defeat to Dinamo Zagreb – and has been in goal for every game under Potter. Impressively, he has kept clean sheets in the previous five and a string of spectacular saves have been produced by the world's most expensive goalkeeper.

So how did Potter and goalkeeper coach Ben Roberts, who also arrived from Brighton, transform Kepa's fortunes in just six weeks?

"I think that's part of the relationship Ben has with him – and he is good at that," Potter explained. "At the same time, the past is the past. You've got to look at the situation now and in my interactions with him, [I've found] a really responsible guy, was not happy with how things had gone, and wanted them to go better. But sometimes life doesn't go that way; it's not a straight line.

"Sometimes you have to suffer and he probably has. He would've liked to have been better but maybe that is an experience that he has that makes him who he is now and maybe the future is a different story. The most important thing is he can embrace those challenges, embrace the suffering he's had to have, and then show his quality. That's why everyone is happy he is performing the way he is. It's a positive story."
