I dont see why not. Djokovic hasnt proven anything on clay.
I'm aware of what Djokovic has done.Robredo has no weapons and he is past his prime. Djokovic is a surging star. i dont think robredo has a prayer.
Djokovic won the Estoril title last year. he also made the semis of the French Open last year.
I remember the exact quote by him - 'it's ridiculous to play at this time' (10 am :lol in his faymoose grumpy tone.Robredo in two.
And btw, nobody should get too excited at the prospect of a Fed-Nalb QF. The Fat One hates getting up early especially when there's good food and a casino in the vicinity. It explains why this is the only major clay event he's never had an impact on.
