Mallorca – The newly crowned Australian Open champion Rafael Nadal would like to end his career with more Grand Slam titles than his permanent rivals Novak Djokovic and Roger Federer. However, he assumes that his 21 trophies will not be enough, the Spanish tennis ace told journalists in Mallorca on Wednesday. Federer and the “Djoker” are hot on Nadal’s heels with 20 titles each. At the recent Australian Open, Nadal’s biggest competitors were absent.
