In 1970, Chelsea Football Club met their northern antithesis, Leeds Utd in the FA Cup final and after a 2-2 draw at Wembley, the replay became known as the dirtiest post war cup final. Chelsea Football Club went on to win 2-1 and the following season, they added the European Cup Winners Cup.
However, as the area became less trendy, the team suffered decline and spent a few seasons in the second division, finally regaining their division 1 place in 1989. Chelsea Football Club added to their haul of silverware in 97/98 season, by winning the League Cup and the European Cup Winners Cup. The club had shocked the football world by the sacking of Ruud Gullit in February 1998, however that was soon forgotten as Gianluca Vialli was appointed the new coach and soon proved his capabillity in this role.
When Vialli was replaced by fellow Italian Claudio Ranieri, Chelsea Football Club began to try and move away from their tag as constant under-achievers, and got a huge boost in that respect in the summer of 2003. Few had heard of Russian billionnaire Roman Abramovich before he bought Chelsea Football Club, but his name was on everyone's lips soon afterwards as he financed a huge spending spree - the like of which the game has never seen - and put Chelsea Football Club well and truly up with the big boys.
