Before Tottenham’s home game against Norwich on Monday, few would have expected the Canaries' assembled lower league players and young hopefuls to walk away with three points from White Hart Lane.
Spurs, seemingly over their slump in form that saw them go five games without a win, looked back on track and ready to resume their duel with Arsenal for third place and a guaranteed spot in the Champions League next season.
However it was Paul Lambert’s side that sprung one of the surprises of the season to date as they picked up just their fourth win in their last ten outings, to leave Spurs’ top four hopes hanging in the balance.
So after a weekend filled with surprises, GMF is here to bring you the biggest upsets of an utterly unpredictable season.
Blackburn 4-3 Arsenal, September 2011
Steve Kean was a dead man walking in September as Blackburn failed to win any of their first four games of the season, prompting protests and boos from supporters aimed at both Kean and the club's owners
Arsenal were hardly any better off as they recorded their worst start to a season in the Premier League era, while their 8-2 defeat against Manchester United ensured they had by far and away the worst goal difference in the league.
The Gunners looked to be finally getting their campaign up and running as Gervinho got proceedings underway, before Yakubu leveled the scores.
Mikel Arteta put the away side ahead once more but once more Arsenal were pegged back, this time through an Alex Song own goal.
Yakubu then put Blackburn ahead for the first time in the game and when Laurent Kolscielny put the ball in his own net, the roof was almost lifted off Ewood Park.
Marouane Chamakh pulled one back for Arsenal but it proved to be too little too late as the pressure was lifted off Kean and placed squarely on Wenger’s shoulders. (Watch Here)
Manchester United 2-3 Blackburn, January 2012
Blackburn were involved in another major upset this season on New Years Eve, becoming only the second team after Manchester City to walk away with all three points from Old Trafford.
United boss Sir Alex Ferguson was looking forward to celebrating his 70th birthday in style with three points, while Steve Kean was looking for respite from the calls of supporters who sought his resignation.
Yakubu gave the visitors a surprise lead from the spot, and the Nigerian put his side in dreamland when he doubled the lead after 51 minutes.
A quick-fire Dimitar Berbatov brace pulled United level inside ten minutes of going 2-0 down, but any fans bemoaning a typical United comeback that would end in an undeserved win were given a shock when Grant Hanley nodded in the winner from close range with ten minutes remaining. (Watch Here)
Newcastle 3-0 Manchester United, January 2012
It was back to back defeats for United as their title challenge appeared to be teetering on the edge, as Newcastle backed up their point at Old Trafford earlier in the season with a sensational 3-0 win over the reigning Champions four days in to 2012.
United, struggling with the blustery conditions of the north east, could barely get a foothold in the game, and were the victims of some clinical finishing from Demba Ba as he slotted home his 15th goal of the season.
Yohan Cabaye then curled home a sublime 30-yard free-kick to double Newcastle’s lead just after half-time before a catastrophic afternoon was rounded off for United when Phil Jones put the ball in his own net just before the full-time whistle. (Watch here)
QPR 3-2 Liverpool , March 2012
While Wigan’s shock victory over Liverpool deserves inclusion as the Latics made it two defeats in two against relegation threatened sides in March, as does Arsenal's 2-1 defeat against Mark Hughes' side, but the manner of Liverpool's loss against QPR makes it one of the great upsets of the season.
With QPR struggling at the wrong end of the table and facing a difficult run in to save their Premier League status, they appeared to be looking down the barrel of a particularly damaging defeat as Liverpool raced into a two goal lead.
A spectacular effort from Sebastian Coates and a close-range header gave Liverpool the early advantage, but that was as good as it got for Kenny Dalglish’s men as the night quickly turned sour.
Shuan Derry put his side back in the game with a goal on 77 minutes before some slack defending from Martin Skrtel let in Liverpool old boy Djibril Cisse to head home the equaliser.
Then, with 90 minutes up Jamie Mackie capitalised on some more atrocious defending to slam home the winner and cause perhaps the biggest upset of the season. (Watch Here)
QPR 1-0 Chelsea, October 2011
In one of the most combustible Premier League encounters this season, QPR were at the thick of the action once more in a game that would have far reaching consequences not just for both clubs, but for the England national team as well.
Heidar Helguson scored the only goal of the game from the penalty spot after ten minutes as Andre Villas-Boas short reign at Stamford Bridge continued to stutter.
Both Didier Drogba and Jose Bosingwa saw red in the heated west London derby, while later John Terry would be charged for allegedly racially abusing Anton Ferdinand, an accusation that would cost him the England captaincy and Fabio Capello his job. (Watch Here)
