Chelsea Fire Coach Jose Mourinho
The 52-year-old Portuguese had been in his second spell at the club as the Blues are currently 16th on the EPL table.
Chelsea finished eight points clear last season and also won the League Cup, but have endured a terrible start to their defence, losing nine of their 16 league games so far.
The former Porto manager’s final match with the Blues was Monday’s 2-1 loss to Leicester City.
Pep Guardiola, Guus Hiddink, Brendan Rodgers and Juande Ramos have all been touted as possible successors.
