Chelsea 1-1 Arsenal (Premier League, December 2006)
Almost two years to the day after that first meeting, this clash signalled the beginnings of a great Premier League rivalry. Chelsea dropped eight points off the pace following the draw, although it would have been even worse had Michael Essiennot produced one of the division's all-time classic strikes. Flamini fired Arsenal into a surprise lead somewhat against the run of play, before Essien belted an effort from range which looked for all the world to be flying wide until it crept in off the post at the last second.
The Ghanian could have won it in added time when he struck the bar, but it was not to be. This heated exchange will also be remembered as the afternoon in which Ashley Cole faced his former club for the first time since making a high-profile switch across the capital, which left Arsenal fans feel just a little aggrieved.


Chelsea 2-1 Arsenal (League Cup Final, February 2007)
Mourinho got the better of Wenger in their first final meeting of sorts in 2005's Community Shield, but this was a bigger occasion with the League Cup on the line. The tension had been mounting throughout in the Welsh capital as early goals from Theo Walcottand Didier Drogba- a man who Arsenal supporters would grow to hate - left the contest delicately poised right until the closing stages.
The Ivorian headed home the winner six minutes from time to land the season's first piece of silverware for his side, but that was just half the story, with some ugly scenes in the immediate aftermath of the goal only adding to the whole drama of this fixture. Jon Obi Mikel, Kolo Toureand Emmanuel Adebayor were each shown red cards for their part in the scuffle which ensued, marring what had been an intriguing cup final.


Arsenal 1-1 Chelsea (Premier League, May 2007)
Chelsea's two-year hold of the league crown came to an end at the Emirates Stadium as they failed to overcome the Gunners, ensuring that Manchester United laid claim to the title for the first time since 2003. The writing was on the wall for the Blues shortly before the interval when Khalid Boulahrouzbrought down Julio Baptistato concede a penalty and earn a red card in the process.
Gilberto Silvamade no mistake from the spot and, despite Essien continuing his goalscoring form against Arsenal with a diving header, Wenger's men were able to hold out for the draw. Missing the talismanic Drogba due to injury, Chelsea's second-half performance was one of their most spirited under the watch of their Portuguese boss, but that was not enough to halt the tears at full time when their hopes of finishing top for a third year on the bounce came to an end.


Chelsea 6-0 Arsenal (Premier League, March 2014)
Having ruined his opposite number's 500th game in charge with a 1-0 win at Stamford Bridge in 2005, Mourinho did likewise on what should have been a truly memorable day for Wenger. The Frenchman's 1000th game at the Arsenal helm ended in pain and humiliation as the Blues ran out 6-0 winnersin West London.
Just seven minutes had lapsed before the hosts had eased into a two-goal lead, with another couple arriving before the break. Some refereeing controversy, which saw Kieran Gibbsdismissed rather than teammate Alex Oxlade-Chamberlainfollowing a handball on the line, could not take the heat away from Wenger, with this his joint-heaviest margin of defeat as manager. For Chelsea, it was their biggest win under the guidance of the self-proclaimed 'Special One', and one that will certainly go down in the record books for years to come.[color=#000099][/color]
