Robin van Persie has denied he will leave Manchester United this summer and claimed he wants to extend his contract when it expires in two years' time. The striker also said he does not have a "bad understanding" with David Moyes.

Van Persie's future is in doubt as he has endured a difficult time during Moyes's first season as manager of the champions. After United's 2-0 defeat by Olympiakos a fortnight ago in the Champions League last-16 first leg in Greece, the Dutchman appeared to criticise some of his team-mates for occupying space he should be operating in.

This could be read as questioning Moyes's tactics and Van Persie's countryman Ronald de Boer last week claimed the 30-year-old could leave United if Moyes does not bolster the squad in the summer with the top-level signings required to ensure a credible title challenge next season. This followed the Guardian's revelation that Van Persie would consider leaving in the summer.

He has now moved to dispel the uncertainty over his future. "The truth is I'm very happy at this club," Van Persie told United Review, the club's programme, in an interview for Sunday's match against Liverpool. "I signed for four years and I'd be delighted to stay even longer, beyond the next two years I have left on my contract. This is how I feel, although it's not what has been suggested in the media."

He also claimed to be content with Moyes and United's squad. "I'm very happy with my team-mates and I'm very happy with my manager and his staff. The sessions we have on the training ground are fantastic and I'm learning a lot from them every day.
