It is brilliant because it is an astounding act of physical excellence - most humans couldn't even get the leg around there most footballers couldn't hope to control the resultant contact enough to send the ball arcing precisely beyond the keeper - but also the achievement of that act of physical excellence requires a mental contortion of similar audacity.
This is also obviously a stupid thing to do. This is obviously a brilliant thing to do. Last Thursday night, against Astaras Tripoli of Greece, Tottenham Hotspur's Erik Lamela scored what he described as the best goal of his career, what his manager described as perhaps the best by any of his players, ever, and what most of the people watching described as 'HOLY HELL DID YOU SEE WHAT HE DID THERE?' He scored a rabona a technique which sees a footballer wrap leg one behind the other, to hit the ball with the 'wrong' foot.
