The defending Olympic champion and in many people's eyes the man to beat again in London.
Nadal has won two of his last three visits to the All England Club - his epic 2008 victory over Roger Federer being somewhat more memorable than 2010's straight-sets success over Tomas Berdych.
That 2008 final was arguably Wimbledon's greatest ever match and many fans will be hoping for a repeat four years on.
Nadal and Federer met recently in the final of the French Open, the Spaniard winning in four sets to claim a record-equalling sixth title at Roland Garros. It was his 10th Grand Slam trophy in all.
Clearly in good nick despite relinquishing his title to Novak Djokovic, Nadal has been able to quickly adapt his game from surface to surface in the past and his outstanding retrieving skills should ensure he is in the mix come the business end of the tournament once more.
At the 2008 Beijing Olympics, Nadal defeated Djokoviæ of Serbia in the semi-finals 6-4 1-6 6-4 and Fernando González of Chile in the final to win his first Olympic gold medal.
