Roger Federer says he enjoyed watching Juan Martin del Potro argue with chair umpire Mohammed Lahyani in his quarterfinal victory over the Argentine. Federer, who is no fan of HawkEye, believes the line calling system takes personality out of the game.
"Back then with the bad calls sometimes you get these arguments," Federer said. "It was just different to see. There was a different momentum, something you kind of talk about sometimes. I don't know, it just has more flair to it, when you have these bad calls from time to time. Now it's just straightforward; you move on. There's a good call, bad call, the worst that can happen is you run out of challenges and the umpire then misses everything and the linespeople too. But the chances of that happening are virtually impossible. I liked it the way it was, and I'm fine with what it is today."
