Arsenal 5-2 Tottenham (2011/12)
Being 10 points ahead of your fiercest rivals with 13 games to go - Tottenham were in dreamland.
Their pleasure was extended when they raced in to a 2-0 lead at the Emirates stadium - a win that would take them 13 points clear and all but assure them a Champions League spot.
The game was the start of the run that saw them win just one out of nine games, losing five and drawing three. They eventually finished fourth behind Arsenal by an agonising one point.
Unimaginably, they still didn't qualify for the Champions League because of Chelsea's unlikely triumph against Bayern Munich.
You can't make this stuff up!
