On the 2nd June 2004, Mourinho signed a contract to become Chelsea manager and during a press conference Mourinho iconically said: “Please don’t call me arrogant, but I’m European champions and I think I’m a special one.” A quote which lead to the media referring to Mourinho as “The Special One”. Mourinho enjoyed a successful first season at Chelsea where he secured his first trophy by beating Liverpool 3-2 (AET) in the League Cup final. However, Liverpool got revenge and prevented Mourinho from winning back-to-back Champions League after a 1-0 aggregate win in the semi-finals where Liverpool went to the final and eventually won the competition. Mouinho didn’t dwell on the defeat and lead Chelsea top their first top-flight league title in 50 years, as well as recording a record at the time 95 points where they only conceded 15 goals.
Chelsea started the following season with a 2-1 win over Arsenal to win the Community Shield and 9 straight victories in the Premier League. Having been top of the Premier League for 36 consecutive games, a 3-0 victory over Manchester United handed Chelsea their second consecutive Premier League title, which was Mourinho’s fourth domestic title in a row.
At the start of the 06/07 season, rumours of a poor relationship between Mourinho and Roman Abramovic lead to speculation that Mourinho could be leaving Chelsea at the end of the season. Mourinho cleared the doubts that he would resign as manager, saying that he would need to be sacked or not offered another contract for him to leave. Mourinho’s third season in charge continued to see success as Chelsea beat Arsenal to win the League Cup and Manchester United to win the FA Cup. However, Mourinho was unable to win 3 consecutive Premier League titles with Chelsea as Manchester United beat them to the title.
Mourinho started the 07/08 season with a defeat to Manchester United in the Community Shield on penalties, where Edwin van der Saar saved all 3 of Chelsea’s penalties. A 3-2 win against Birmingham City gave Chelsea a record 64th unbeaten home game in a row. Surprisingly, Mourinho was only in charge for 6 Premier League games that season as he left Chelsea by mutual consent on the 20th September 2007, 2 days after Chelsea’s 1-1 draw with Rosenborg in the Champions League. Mourinho left Chelsea having won 6 trophies and was replaced by Chelsea’s director of football, Avram Grant.
