Rafael Nadal: 'I want to be more aggressive'

World number two Rafael Nadal has revealed that he is trying to play a more aggressive game since recovering from injury.

The Spaniard stormed past the second round on Thursday by beating Rogerio Dutra Silva 6-2 6-1 6-0 at Flushing Meadows.

Nadal, who could face Roger Federer in the quarter-finals of the tournament, admits that his recent injury hell has caused him to go in search of a new tactic.

"I'm trying to play more aggressive," Nadal told reporters.

"I didn't have time to practise a lot because I was injured for seven months and when I started to feel better I started to compete.

"I need to play more aggressive - I'm trying to work on this my whole career but it's more mental than a training thing."

Nadal will face Croatia's Ivan Dodig in the third round.
