The Blues have lost five times in the last eight league matches and the performances have not gone down well with the board.
Lampard spent over 200 million on new players in the summer and started the season on a good note before the slump started with the loss to Everton.
According to a statement on the club’s website:
‘There can never be a good time to part ways with a club legend such as Frank, but after lengthy deliberation and consideration it was decided a change is needed now to give the Club time to improve performances and results this season”.
Roman Abramovich said,
“This was a very difficult decision for the Club, not least because I have an excellent personal relationship with Frank and I have the utmost respect for him’.
“He is a man of great integrity and has the highest of work ethics. However, under current circumstances we believe it is best to change managers.
“On behalf of everyone at the Club, the Board and personally, I would like to thank Frank for his work as Head Coach and wish him every success in the future. He is an important icon of this great club and his status here remains undiminished. He will always be warmly welcomed back at Stamford Bridge.”
Tuchel is expected to be announced as the new Chelsea coach.
