Roger Federer has exclusively told CNN he feels he could beat reigning champion Rafael Nadal at this year’s French Open in Paris, because despite winning the last four tournaments the Spaniard is "only human." The world number two is hoping this year will prove to be a turning point after suffering three consecutive final defeats to Nadal at Roland Garros. “He’s won four straight times here in Paris which shows how tough he is, but if you play him the right way there will be chances, he is only human and we wait for that moment when he is not at his best; hopefully that will be this year,” the Swiss said. The 27-year-old certainly started the right way if he is to mount a succesful challenge, beating Alberto Martin 6-4 6-3 6-2 in under two hours to advance to the second round, setting up a clash with either Jose Acasuso or Santiago Ventura.
