Jose Mourinho at Chelsea - season by season
Former Chelsea boss Jose Mourinho returns to Stamford Bridge on Sunday for the first time since taking over at Premier League rivals Manchester United.
Here, Press Association Sport looks at his seven seasons in charge of the Blues.
Arriving at Stamford Bridge having won the Champions League with Porto, the self-proclaimed 'Special One' continued his success by guiding Chelsea to their first title in 50 years as they finished 12 points above nearest rivals Arsenal. The Blues also beat Liverpool at the Millennium Stadium to lift the League Cup but they were later knocked out of the Champions League by the same opposition following Luis Garcia's contentious goal in the second leg of their semi-final.
The Portuguese proved he was not a one-season wonder in England as he led Chelsea to back-to-back Premier League titles. He endured more European frustration though with the Blues beaten 3-2 on aggregate by Barcelona in the last 16 of the Champions League.
Chelsea fell six points short of retaining the title but they did clinch a domestic cup double by beating Arsenal in the League Cup final at Cardiff before becoming the first side to lift the FA Cup at the new Wembley with an extra-time victory over league champions Manchester United. There was more Champions League disappointment as old foes Liverpool defeated them on penalties at the semi-final stage.
Chelsea made an indifferent start to the season and amid reports of an increasingly strained relationship with Chelsea owner Roman Abramovich, Mourinho left the club by mutual consent at the end of September. His replacement, Avram Grant, took the Blues to second spot and the brink of Champions League glory before they were beaten on penalties by Manchester United in Moscow.
Mourinho returned on a four-year contract in the summer of 2013 to replace Rafael Benitez after time away at Inter Milan and Real Madrid. He finished third in the league in his first season back and was once again frustrated in the Champions League by a semi-final defeat to Atletico Madrid.
Mourinho delivered a th ird and final Premier League trophy for the Blues as they finished eight points clear of Manchester City. The season also brought another League Cup success after a 2-0 victory over Tottenham at Wembley.
Mourinho's final season at Stamford Bridge was overshadowed by his clash with club doctor Eva Carneiro and reported problems with some of his star players. He was sacked after a 2-1 defeat at eventual champions Leicester in December, Chelsea's ninth Premier League loss from their opening 16 games.
