Two years ago, Kepa Arrizabalaga refused Maurizio Sarri order to be substituted

Chelsea fans will not forget the moment when Kepa Arrizabalaga refused to be substituted.

It was two years ago under former Italian manager Maurizio Sarri, when Kepa was substituted during a league Cup final against Manchester City. 

Sarri called for Kepa to be subbed for Willy Caballero who was a preferred option for penalty duties. 

The game against Pep Guardiola side was stretched to penalty, but Kepa shocked the world when he refused to be subbed and remained on the pitch. 

Chelsea went ahead to lose to Manchester City at the end of penalty shoot out.
