Rafael Nadal at the airport in Palma de Mallorca. Rafa on his way to Abu Dhabi for Mubadala World Tennis Championship 2015.

Rafa says after several months w/o having continuity & hardly competing, there's work to do. Step by step, he hopes to reach required level.
It won't be easy but he'll have the right positive attitude & accept the small problems that can appear, so that they are as few as possible
He's motivated to be back doing what he loves most,which is competing & being back on tour w/the feelings that only competition can give you
There are only 2-3 weeks left for AO & hopes to arrive well, but he's aware 2 weeks might not be enough, so that he feels he's back at 100%.
Season doesn't end at AO. In fact, period from end of AO till end of RG is the most important for him & week by week he'll try to be at 100%
Two weeks in Abu Dahbi & Doha,where he'll play good level players,should help him to find good physical&tennis feelings & competition rhythm
Asked if injuries are now history,he says you never know & it's necessary to be cautious & always ready to accept they're part of his career (translated by @genny_ss)
