Former Chelsea assistant manager Gianfranco Zola has spoken about the infamous incident between boss Maurizio Sarri and goalkeeper Kepa Arrizabalaga.

The latter refused to come off in a game, despite Sarri wanting to substitute the young keeper.

The two eventually made up, but it was an incident that caught the football world by storm last season.

And Zola defended Kepa from that behaviour.

"There was a lot of confusion. We were in the final minutes of the game and he tried to waste time. Then he threw himself to the ground," said Zola to Goal.com.

"We wanted to make the change.

"He was injured and we were approaching penalties.

"On the bench was Willy Caballero, who is very good in those situations, and knew all the Manchester City players of his time there.

"He did not understand, there was a great misunderstanding. We were also pressured because we wasted time.

"What he did was not good, but he apologised and did not go any further. They are things that can happen."
