Nothing new Federer and Nadal plays for money. Nadal complains about the schedule but plays tons of Exhibitions from US to Dubai.
He plays the relatively small tournament that he's closest to (Barcelona), plays Madrid even though the conditions haven't favored him in the past and he also routinely plays Davis Cup. He does plenty for the Spanish events. Valencia should be happy with their native son playing there.
And Nadal probably shouldn't be playing any Euro indoor 500s anyway.
Uhmmm Madrid is in Clay and is a masters 1000, why compare.
So now an Active Player like David Ferrer has rights of an ATP Tournament. This is Clearly a Conflict of Interests.
Djokovic uncle runs the Serbia Open when it was active.
