This is more to do with Del Bonis not doing shit anymore.
A good Murray on clay would probably push (and probably beat) this Nadal to be fair. Before any of you Rafatards actually laugh at that comment, go watch a replay of the second set between them in Monte-Carlo 2 years ago.
I doubt we'll see this Rafa at Roland Garros though, history would suggest as soon as he loses to a mug he'll say his knee has played up again and take another few months off.
Nadull is playing better tennis in this 2nd set than he did during most of his career.
Nah, Rafa isn't actually very sharp today, leaking quite a lot cheap UEs that he usually wouldn't. Del Bonis just can't put him under any pressure. Looking at the draw, the only potentially interesting match Nadal could have here is vs Chardy. When 'on, Chardy's forehand is one of the biggest weapons in tennis, even if not at his best he would still test Rafa's movement and sharpness far more than anyone else in the draw.
This is why Fede hasn't cracked the top 100 despite his potential. When one thing goes against him, he crumbles into his shell.
If Nadal's leaking errors (something you never associate with him) he should be being tested but he isn't.
He's Del Potro... only with even slower movement and without the power on his shots to keep oppponents at bay It's going to be tough for him to find a style of play/strategy that can make him successful on the ATP tour
