(Assessing their form on this Middle Sunday here at Wimbledon, if Rafa played Djokovic now, Rafa would win in 3, and with several breaks. Djokovic's serve looks weak, and his mind appears all over the place and completely psychotic. People forget, Rafa won the 1st set at Indian Wells, Miami [and lost in a 3rd set tiebreaker]. Transfer that into a slam environment and best-of-5 where Rafa has only lost one match after winning the 1st set, and on grass, Rafa is a class above Djokovic.
Contrary to popular belief at Roland Garros [and much of the clay season where Rafa played at a lower level than previous years] and Queens, nobody can say Rafa is looking jaded now, the extreme opposite is true. Despite playing several less matches than Rafa this year, Djokovic appears to have lost it mentally and physically, if his Baggy match is anything to go by, while Rafa has reached a level of sharpness not seen since June 2008, now boasting 104 winners, just 24 unforced errors and has only been broken once
I have no real interest in Federer, Murray, others can assess those
