An italian tv station decided to make this interesting juxtaposition between Federer and Safin when they get angry. Safin's definitely more emotionally invested in his smashing. One would think Safin gets more excited when he hits a good shot (to counterbalance his negativity), but instead he just seems relieved. A bit of a pessimist but that's the Marat we've all come to know and love..
And Federer... boy has he changed
