Roger Federer returning the favour

Roger Federer letting Nadal waiting at the net and before as Rafa does every time. He said then: "I just thought that today we'll do it in a different way. Players let him do too may things. They let him determine their rhythm. When you play him, from the moment that you leave the locker room till the moment of the first ball exchange 20 minutes have passed. They should normally be 5 to 10 minutes. Now I decided to take my time and see how patient he was".
