Mark Clattenburg is widely regarded as the best referee in England but he came in for huge criticism after deciding to award a penalty to Tottenham during their 2-1 win against Manchester City.
There was very little to choose from between the two sides in the first-half, with both sets of players realising the importance of the clash in the title race.
But, in the 52nd minute, the stalemate was broken. Not by a moment of magic but by a very questionable refereeing decision.
A Danny Rose cross appeared to hit the ribs Raheem Sterling's as he attempted to block the ball just inside the box.
There were very few appeals for a penalty from the Tottenham players but Clattenburg decided that Sterling had deliberately handled the ball and pointed straight to the spot.
Harry Kane cooly tucked away the penalty, while City players and fans were left cursing the decision of the referee.
As expected, City fans - and neutrals - took to Twitter to question the extremely controversial decision.
While many of the tweets were too explicit to include, here are a few of the cleaner ones:
City fans started to forget about the poor refereeing decision when substitute Kelechi Iheanacho came off the bench to equalise for the home side in the 74th minute.
However, eyes were cast back in Clattenburg's direction when Christian Eriksen restored the lead for the away side with just seven minutes remaining.
The win leaves Spurs just two points behind league leaders Leicester after the Foxes lost late on against Arsenal.
