Thanks to Willy Canas for this about Chucho and RR.
"Maybe in another circumstance I would have gone on, I don't know. I didn't like the RR, I hope they keep the traditional system. Perhaps it is interesting for the people, but if I lose I want to think in the next tournament, and thats it."
thnks WillyC for this quote: I think Chucho is right about RR and all the players thinks more or less the same. Some other poster said that it is also worse for the players because they have to play more matches. ATP is already very tiring to add even more matches.
I hope they keep the old format, as Chucho said.
