Chelsea legend and former assistant coach Gianfranco Zola admits he's been surprised by the demise of Kepa Arrizabalaga.
The Spaniard has been replaced as Chelsea's number one goalkeeper by Edouard Mendy.
"I'm very surprised," Zola told talkSPORT. "I know he is very young and he came to Chelsea for big money and that is a big burden to carry on your shoulders, and in a way this is probably affecting him.
"He has to pick himself up and do what he can do and show people he is different, because I believe he has got potential."
