A year before, just around the AusOpen where Rafael Nadal played two 5set matches against Verdasco and Federer, WADA announced the new anti-doping rules which require athletes to inform testers of their location every day. I don't remember when these rules was applied, but I remember that Nadal and Murray were against the rules and they even attack them. Soon after that in the next tournament in Rotterdam Nadal announce his knee problems, and after that till now Nadal won only 4 ATP titles (Indain wells, Monte Carlo, Barcelona, Rome.)
I am just curios, how do you think is it possible the new WADA anti-doping rules to be connected with the Nadal bad performance ?
