Chelsea have axed Frank Lampard after only 18 months.
He is set to be replaced by former Paris Saint-Germain boss, Thomas Tuchel.
In a statement, Chelsea said “results and performances have not met the club’s expectations, leaving the club mid-table without any clear path to sustained improvement”.
Lampard, who is the club’s all-time leading goalscorer, enjoyed a good first season as Blues boss.
He led the club to the FA Cup final and secured qualification for the Champions League.
But after being given more than £200m to spend on new players in the summer, the Bues find themselves ninth in the Premier League after 19 games, 11 points behind leaders Manchester United and five points off Liverpool in fourth.
Lampard took the side on a 17-game unbeaten run, but away defeats to Everton, Wolves, Arsenal and Leicester and a 3-1 home defeat to Manchester City have cost him his job.
