1: Ice-man Roger Federer lost his temper and was involved in a rare dispute with a chair umpire on Thursday during his French Open match against Marin Cilic. It was a surprise to see him so angry – but even though he is known to be very mild-mannered, this was not the first time he has blown a fuse on court. Back in 2005, he threw his racket on the floor during the NASDAQ-100 Open final against Rafa Nadal.
