Chelsea are searching for a new manager after Jose Mourinho sensationally left Stamford Bridge by mutual consent on Wednesday night.
Mourinho joined the Blues in June 2004 after guiding FC Porto to Champions League glory.
In his three full seasons with Chelsea he won five major trophies - two successive Premiership titles, two Carling Cup successes and victory against Manchester United in last season's FA Cup Final.
However, he failed to guide the club past the semi-finals of the Champions League and his final game was Tuesday's grim 1-1 draw with Norwegian side Rosenborg.
Without the injured Didier Drogba in recent weeks, Chelsea had looked toothless in attack and the draw against Rosenborg followed a defeat at Aston Villa and goalless stalemate with Blackburn.
Mourinho left after the club held a crisis meeting on Wednesday to discuss the side's indifferent start to the new season.
His relationship with Blues owner Roman Abramovich has been poor for some time and he had been tipped to leave the club at the end of last season.
Mourinho, who still had three years left on his contract, texted several senior players on Wednesday night to confirm his departure.
Former Israel coach Avram Grant, recruited in the summer as director of football, is expected to take charge of the side for Sunday's Premier League clash with Manchester United.
Former Chelsea player Didier Deschamps has already been linked with the Stamford Bridge vacancy as has Russia manager Guus Hiddink and Sevilla coach Juande Ramos.
Mourinho took charge of 185 games during his time with the Blues, winning 124, drawing 40 and losing 21. Chelsea are currently unbeaten in their last 60 Premier League games at Stamford Bridge under Mourinho's guidance.
