Denis Zakaria admits he didn't know he was moving to Chelsea until deadline day.
The Switzerland midfielder is on-loan at the Blues from Juventus.
Zakaria told Blick: "It all happened very quickly. I didn't know a move to Chelsea was possible until six hours before the end of the transfer window.
"I packed my things and waited for the contracts to be signed. Then I did the medical check in Turin and it was through, it was very close.
"Thomas Tuchel was one of the reasons I went to Chelsea, he's a great coach.
"But now we haven't had much time with him, but that's football. Everything goes fast.
"I might have a new chance with the new coach, about whom I've heard a lot of good things. I will work a lot to get my place."
