Nikolay Davydenko: "The younger generation is not good technically"
Nikolay Davydenko , former tennis world No. 3, on the NextGen and his matches against Roger Federer, Rafael Nadal and Novak Djokovic.

The current top players, apart from Djokovic and Nadal, "are technically not good," said Davydenko. "It's gotten more physical - strong serves, hard groundstrokes - but we still see that Nadal and Djokovic can control the new generation. They're still winning slams and beating guys ten years younger than them, which is amazing." , said the 41-year-old. "Anyway, I don't feel that the new generation is playing at an incredible level."
