Caroline Wozniacki happy with Rory McIlroy and her form

Caroline Wozniacki rubbishes claims that her relationship with Rory McIlroy has nothing to do with her sliding performance and admits to be happy with her form.

Since they met McIlroy has won two majors but been criticised for his inconsistency and Wozniacki has slipped from No1 to No9, prompting the inevitable suggestion that their relationship has been bad for their respective games. It is a suggestion that both reject, the Guardian reported.

Both make it an effort to see each other, in their separate day jobs, to realise that the relationship is still going strong.

McIlroy is a regular visitor to the tennis circuit and Wozniacki is often seen inside the ropes at the world's top golf events.

She goes on to say that what McIlroy and she have is very special, and they are trying to work their schedule, which been working out well so far.

The pair are favourites of the paparazzi but refreshingly, they don't seem to be seeking attention as some other high-profile couples have done in the past.

Wozniacki has underachieved when it comes to grand slam events. Her only grand slam final appearance was at the 2009 US Open.

Some may feel that Wozniacki is now more famous for being McIlroy's girlfriend than for her tennis exploits. But the Dane maintains that any criticism of her abilities, of her relationship and of any aspect of her life is something she has got used to.

Though Wozniacki says she is unlikely to be playing beyond 30, she still believes in her ability and believes winning a grand slam is possible.

Having shrugged off a few niggling injuries, she is fully fit once more and is determined to do well.

She said that, if it does not happen, she will not fret about what might have been.
