Roger Federer ’s former coach has claimed that Carlos Alcaraz “lost his joy” this year - with Novak Djokovic being held responsible. The Spaniard won two Grand Slam titles over the summer but struggled during the North American hard-court swing and didn’t get out of the group stage at the recent ATP Finals.

There are not many players who can say they have defeated all three of Rafael Nadal, Novak Djokovic and Roger Federer in Grand Slam matches. Andy Murray, Stan Wawrinka, Tomas Berdych and Jo-Wilfred Tsonga are the only four tennis stars to have achieved that remarkable feat.
