Washington: Top tennis coach Nick Bollettieri has claimed that 17-time Grand Slam Champion Roger Federer is in a very vulnerable state ahead of his opening match at the US Open on Monday.

According to CNN, Bollettieri expressed that Federer is great for the game and well respected, but now that he has moved to No.7, he is in a vulnerable state.

Federer regained the world No. 1 ranking with last year`s record-equaling seventh Wimbledon title, but since then he has had difficulties with both his game and his fitness, and is seeded just seventh for the season`s closing grand slam in New York, the report said.
