Davydenko calls out Federer, backs Nadal's claim

MELBOURNE, Australia (AP) -- Nikolay Davydenko says he doesn't know why Roger Federer is not backing other players in their complaints about issues affecting the men's game.

Davydenko, the Russian former world No. 3, spoke a day after Rafael Nadal criticized his Swiss rival for sitting back while others speak out about issues including the overcrowded schedule and the distribution of prize money.

Davydenko says 16-time Grand Slam champion Federer doesn't want "any problems" because "he's a nice guy, he's from Switzerland, he's perfect."

Nadal says the majority of players are in agreement that there are issues that need resolving. Davydenko says one of those is an increase in prize money at Grand Slam tournaments.
