Despite being the second best tennis player in the world, with 12 grand slam singles titles to his name, Novak Djokovic has been suffering a bit lately; losing his world number one ranking to (Sir) Andy Murray and, subsequently, the invincible aura that he carried for so long.
That's not to say that the wiry Serb doesn't still have the goods, it just means that, well, it means that things like the below are beginning to creep into his game.
While Djokovic went on to win his first round match in Acapulco against world number 62, Martin Klizan, the sight of him totally miscuing such a rudimentary shot (in relation to his talent) was odd; considering his previous reign of superiority.
In the end, at least he got the win, and at least Federer and Nadal had something to laugh about...
Tennis: a cruel and fickle business.
