Chelsea attacker Kai Havertz admits he didn't see the dismissal of Thomas Tuchel coming.

Hours after a Champions League loss away at Dinamo Zagreb, the German was relieved of his duties despite a busy summer of transfer activity at Stamford Bridge.

Graham Potter has since been appointed as Tuchel's replacement, overseeing a 1-1 draw with RB Salzburg in his first game in charge.

Havertz was a key player under his compatriot and said: “Me too [it surprised me]. Especially when you consider how we've played in the past year and a half and what we've won.

“With the current sixth place in the table, you can't speak of a messed up start to the season, especially since we have many newcomers who first have to acclimatize. But football is very fast-moving, a lot can happen at any time.

“Our new coach has made a very good impression, we have a great squad. I think we are in for a good time."
