US OPEN 2015: Nadal says his struggles are on him, not team

NEW YORK (AP) Rafael Nadal says the responsibility for his recent struggles rests with himself, not his support team.

Coached by his uncle, Toni Nadal, he has won 14 Grand Slam titles. But 2015 has been a rough year in his return from injury.

Nadal noted Tuesday he has had ''an amazing career with the team that I have today, the same team from the beginning.''

He adds: ''So my feeling is if something's not working well it's not because of your team - it's because of myself. The one thing I have to change is myself.''

That means playing more aggressively, and Nadal comes into the U.S. Open feeling much more confident in his game even if it hasn't shown in the results.

Considering he was publicly voicing self-doubt before the French Open, that is a positive step.
