Manchester United visit Stamford Bridge on Sunday to take on Chelsea in the most widely-anticipated match of the 2012-13 English Premier League season so far. This clash brings together the two most successful English clubs of the last decade.
Since 2003, Manchester United have won four Premier League titles, one UEFA Champions League, one FA Cup and three League Cups. Additionally, they reached another two Champions League finals.
In the same time period, Chelsea have racked up three Premier League trophies, one UEFA Champions League, four FA Cups and two League Cups. They also reached another Champions League final in 2008, which they lost to United.
The head-to-head record between the teams in the post-Roman Abramovich era reads as follows: Played 27: Manchester United wins 9, draws 7; Chelsea wins 11.
Even without the context of the clubs' success in the recent past, this game is a face-off between the top two teams in the Premier League table currently.
Chelsea have made their best-ever start to a Premier League season and are currently four points clear at the top. United, on the other hand, have racked up wins to stay in second place, despite a creaky defence and issues with the midfield.
As a build-up to this all-important clash at Stamford Bridge, here is a look at 10 of the most significant matches between the two clubs in the last decade.
