Chelsea have sacked manager Frank Lampard after 18 months in charge, with former Paris St-Germain boss Thomas Tuchel expected to replace him.

Lampard, 42, leaves with the club ninth in the Premier League after last week's defeat at Leicester City, having won once in their past five league matches.

His final game was Sunday's 3-1 FA Cup fourth-round win against Luton.

Lampard was appointed on a three-year contract when he replaced Maurizio Sarri at Stamford Bridge in July 2019.

The former Chelsea midfielder guided them to fourth place and the FA Cup final in his first season in charge, and a 3-1 win against Leeds at the start of December put the club top of the Premier League.

The club made an announcement on the official website:
"Chelsea Football Club have today parted company with Head Coach Frank Lampard.

This has been a very difficult decision, and not one that the owner and the Board have taken lightly."

"We are grateful to Frank for what he has achieved in his time as Head Coach of the Club. However, recent results and performances have not met the Club’s expectations, leaving the Club mid-table without any clear path to sustained improvement.

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.”

Lampard did not sign a single player during his first season as the club were operating under a transfer embargo, but spent more than £200m on seven major signings last summer, including £45m on Leicester's Ben Chilwell and £71m on midfielder Kai Havertz from Bayer Leverkusen.

It is the most Chelsea have spent in one summer, eclipsing the £186m they invested at the start of the 2017-18 season.

Lampard is Chelsea's all-time record scorer, with 211 goals for the club between 2001 and 2014, and is also joint-seventh on the list of England players with the most caps, having made 106 appearances for his country over 15 years from 1999.
