Jose Mourinho is out as Chelsea manager.
Only seven months after winning the Premier League title, the Portuguese coach left with the club languishing one point above the relegation zone.
Chelsea says "both Jose and the board agreed results have not been good enough this season and believe it is in the best interests of both parties to go our separate ways."
Chelsea has lost nine of its 16 league games, with Mourinho's last match a 2-1 loss to Leicester on Monday.
After easing to the league title in May, Mourinho was awarded a new four-year contract.
First hired by Chelsea in 2004, Mourinho won the league twice before a fall-out led to his firing three years later. He was brought back in 2013 by owner Roman Abramovich.
