Nadal is due to play Nicholas Mahut later today at the US Open. He's played serve and volleyers at Wimbledon or at least guys who've attacked him like Philipp Petzschner. He played Giles Muller this year at Wimbledon which he didn't enjoy. I think it's a shame Nadal will not play a real top class serve and volleyer throughout his career. Someone who cannot just serve and volley of course, but can return serve well, can put pressure on him from the baseline and then close the net. Players like Sampras, Becker, Rafter, Krajicek spring to mind. It's a pity Nadal will not face players of this calibre of skill or that young payers are not coming through with this type of skill which would have added a different dimension to Nadal's matchups at the top level. Your thoughts.
