Corner kicks are a crucial part of football.
They're a regular source of goals for teams that can execute them properly, hence why there have been numerous attempts to add unique twists to the conventional corner kick routine.
Arsenal icon Santi Cazorla famously once took a corner with his supposed 'weak foot' in order to confuse the opposing defenders.
But there's one Premier League corner kick routine from 2009 that tops any other and it was criminally disallowed after it resulted in a goal.
The architects were Sir Alex Ferguson's Manchester United in a game against Chelsea.
During the Red Devils' 3-0 win over the Blues, Cristiano Ronaldo thought he had scored legally from an ingenious corner routine.
It was pulled off so masterfully that Howard Webb had no idea what was going on, eventually ordering a re-take despite the goal being well within the rules.
Wayne Rooney dribbles over to the corner flag and appears to leave the ball for Ryan Giggs.
However, no one realised that Rooney had placed the ball on the spot and gently touched it to make it 'live'.
Giggs then dribbles towards the penalty area, catching the Chelsea defenders napping before setting up Ronaldo for an easy headed finish.
Fortunately for United, they would go on to score from the re-take, with Nemanja Vidic nodding home from a traditional left-footed cross from Giggs.
Two years later, Blackburn Rovers imitated United's corner routine in a 3-3 draw with Wigan and this time, Andre Marriner awarded the goal.
Morten Gamst Pedersen dribbled the ball all the way into the box after Yakubu had made contact with it by the flag, with the Norwegian teeing up Junior Hoilett to head home from two yards.
It seems quite amazing that the routine hasn't been attempted again more recently in the Premier League!
