Rafa is not at all playing his best clay tennis as some foolish VB members claim to be.
He is not even at the 2017 level.
Hard hitting and deep shots can trouble him as we have seen, a little bit of this show vs Garcis Lopez yesterday, though it was a one sided match but still rafa's weaknesses were clearly visible...
The bloody damn clay field is so depleted that almost no players are able to defeat him, and the ones who are capable to do so are messed up with injuries (djoker, murray and stan), or
dont like clay much (delpo), or
very small in frame so can not grind with rafa for 4/5 sets (goffin and kei nishikori), or
have mental block or no mind(dimitrov and fognini), or
have full capacity of taking down rafa but foolishly bashes balls and always gets gassed out before reaching bull(dominic), or
totally idiot(zverev), ......
I will be surprised even if someone takes a set off rafa
