Thomas Tuchel says he is "honoured" to have been part of Chelsea's history and his time at the club will "always have a special place in my heart".
The Blues appointed Graham Potter from Brighton as his replacement the next day, with compensation for the Englishman his staff totalling £21m.
Tuchel said he was "devastated" his time at Chelsea had come to an end.
The former Borussia Dortmund and Paris St-Germain boss exited Stamford Bridge after winning three trophies in 20 months, including the 2020-21 Champions League.
But a club statement on Wednesday said the new owners believed it was "the right time" to bring in a new head coach.
