Hamburg midfielder Rafael van der Vaart has dropped a hint that he will move to Chelsea if they put in an offer in the summer.

The 25-year-old Holland international is eyeing a move out of the Bundesliga club at the end of the season after reportedly having been denied a move to La Liga outfit Valencia last summer.

"I would like to have everything cleared up early, but we cannot agree in July that I will be staying - that would be unrealistic," he told Sport Bild magazine.

"What happens when Chelsea or another top club comes along on August 21 and offers 30 million euros?

"I would want to move, even at the very last minute of the transfer window."

"Hamburg made me a great offer last year and I turned it down because my aim is to move to a big club where I can improve and win trophies," added van der Vaart.

"My opinion will not change."
