* Arsenal 3-2 Manchester United (FA Cup final, May 1979)
Nicknamed ‘The Five-minute Final’, the climax to the 1978-79 FA Cup burst into life in its final stages at Wembley Stadium. Arsenal were 2-0 up and cruising when Gordon McQueen pulled a goal back in the 86th minute. Two minutes later Sammy McIlroy equalised, only for Arsenal to race straight back down the pitch, with Liam Brady crossing from the left for Alan Sunderland to slide home an 89th-minute winner.

* Manchester United 0-1 Arsenal (First Division, Oct 1990)
The enmity that developed between the teams in the 1990s and 2000s can be traced back to this fiery encounter at Old Trafford. A 21-man brawl sparked by a foul on United’s Denis Irwin by Arsenal left-back Nigel Winterburn saw the visitors deducted two points and the home side one. The game’s only goal, which became something of a sidenote, was scored by Arsenal’s Swedish winger Anders Limpar.
