Federer keeps marching on

With Nadal out through injury, looks like Federer has one less obstacle in his way to claim a record 15 Grand Slam. if he makes it, he will be the most successful tennis player of all time, in so far as number of Grand Slam titles won. The only person who looks capable of stopping him would be Andy Murray but can he do it? Not for lack of talent but the pressure and expectations. He needs to shut them all out and concentrate on his own game. As usual, it easier said then done.
