Roger Federer vs Tomas Berdych prediction

No doubt that Federer is one of the legend of active tennis. He made a very good commentary in his country in January. He mentioned that he knows his body and he is not young anymore. That's why he would attend only Grand Slams and some major events. As a result, he did not attend French Open. It was very tired and creates a lot tension on his ankle. He helds most title in Wimbledon. Else everything, his motivation has increased a lot after Djokovic and Nadal eliminated so far. Federer has big edge over Tomas, has won 15 of last 16 sets that they have clashed. Tomas is having mental problems against Top-5 players. He failed to take a set in last 20 sets against these elite players. I see straight sets victory and not to play tie breaks in these final game.
