Since Arsene Wenger's arrival at Arsenal, the clash between the Gunners and Manchester United has been the key Premier League fixture of the season. Whilst Chelsea have also been prominent during the Premier League years, these two teams have played out a number of classics in recent years.
Whilst we start off with a couple of old school cup ties, the majority of the rest of the classic matches involve crucial encounters at the back end of seasons. And in most cases the winner went on to take the spoils.
In preparation for Monday's game at Old Trafford, here are 10 classic Manchester United-Arsenal fixtures.
1. Arsenal 3 - Manchester United 2 (FA Cup final, May 12, 1979). Nicknamed the 'Five-minute cup final', Arsenal looked destined to win easily thanks to first-half goals from Brian Talbot and Frank Stapleton. United staged a remarkable comeback, scoring on 86 and 88 through Gordon McQueen and Sammy McIlroy. But back came Terry Neill's Arsenal with Alan Sunderland, sporting a nifty perm, sliding home a dramatic winner with seconds remaining of normal time.
2. Arsenal 2 - Manchester United 6 (Rumbelows Cup, November 28, 1990). One of the finest results in Sir Alex Ferguson's early years at Old Trafford. Arsenal would go on to win the league with a super-tight defence led by George Graham. United were irresistible on the counter attack and Lee Sharpe announced himself as an emerging player with a hat-trick. Clayton Blackmore, Mark Hughes and Danny Wallace were also on target in the rout.
3. Manchester United 0 - Arsenal 1 (Premier League, March 14, 1998). Marc Overmars scored the winner with 11 minutes to go but in retrospect it is easy to see just what significance this match would have on English football. A stunning surge from the Gunners in the second half of the season enabled them to overturn United to win the league and secure Arsene Wenger's first league title in English football.
4. Arsenal 1 - Manchester United 2 (FA Cup semi-final replay, April 14, 1999). The last ever FA Cup semi-final replay was one of the finest matches ever produced in English football. After the two sides had played out a 0-0 draw three days before, the second match at Villa Park had everything. David Beckham put United in front with a trademark long-range effort. Dennis Bergkamp's deflected effort brought Arsenal square. But the Dutchman would see his injury-time penalty dramatically saved by Peter Schmeichel. And then Ryan Giggs scored one of the greatest individual goals of all time...
5. Manchester United 6 - Arsenal 1 (Premier League, February 25, 2001). After their treble win in 1999, United dominated domestically and this was one of their finest performances as they put Arsenal to the sword. Dwight Yorke took the plaudits whilst Roy Keane, Ole Gunnar Solskjaer and Teddy Sheringham also got in on the act.
6. Manchester United 0 - Arsenal 1 (Premier League, May 8, 2002). Arsenal completed the double with another famous win at Old Trafford. Sylvain Wiltord claimed his place in Gunners folklore with the only goal of the game after Barthez had parried a Ljungberg shot. The victory ensured Arsene Wenger's side went unbeaten during their away matches in the 2001/2002 league campaign.
7. Manchester United 2 - Arsenal 0 (Premier League, October 24, 2004). The Invincibles came unstuck in a dramatic match which also reportedly featured Cesc Fabregas throwing pizza over Sir Alex Ferguson in the dressing rooms post-match. Arsenal's 49-game unbeaten record came to an end thanks to a late penalty by Ruud van Nistelrooy (making up for his miss a year earlier) and a tap-in from Wayne Rooney on his birthday.
8. Arsenal 2 - Manchester United 4 (Premier League, February 1, 2005). Roy Keane's tunnel rant at Patrick Vieira set the tone for this match as United eased to an impressive victory at Highbury. Patrick Vieira's opener was cancelled out by Ryan Giggs, Dennis Bergkamp regained the lead for the Gunners but a brace from Cristiano Ronaldo and a chip (!) from John O'Shea secured all three points and halted Arsenal's title charge.
9. Arsenal 0* - Manchester United 0 (FA Cup final, May 21, 2005). In contrast to the 1999 semi-final replay this was one of the worst FA Cup finals ever. Manchester United made all the running in Cardiff but could not find a way through an Arsenal side that really struggled with just Dennis Bergkamp up front on his own. Patrick Vieira would score the winning penalty to secure Arsenal's last major trophy until this year's Carling Cup (?).
10. Arsenal 1 - Manchester United 3 (Champions League semi-final second leg, May 5, 2009) After securing a slim 1-0 first leg lead United headed to a noisy and packed Emirates with the tie on the line. A blistering early spell from the side in blue, consisting of a Ji-Sung Park opener and brilliant Cristiano Ronaldo free-kick secured the win in the opening minutes. Ronaldo added a brilliant break-away third with only Darren Fletcher's sending off spoiling an incredible performance.
