No. You chose Wawrinka because he beat your fave. And because you feel the need to bash Federer's so-called weak era, while the real weak era is occuring right now.Wawrinka.
Nalbandian is extremely overrated because he is Federer's contemporary.
So what you are saying is that Nalby's backhand is same as Wawrinkas?When both are on fire Wawrinka takes this by a mile, the only similarity they share is the fact they are both fat, or atleast look like it.
Wawrinka has a way better serve and forehand, other shots are of the same caliber.
