Madrid, July 23 (DPA) Real Madrid are clearly annoyed at unwanted striker Klaas Jan Huntelaar finally turning down a lucrative offer from VfB Stuttgart.

After more than two weeks of ardous negotiations, it seemed that Huntelaar was finally set fair to sign for Stuttgart for around 18 million euros (25.57 million dollars).

The Dutch forward had requested not to go to Real's pre-season training camp in Ireland in order to negotiate with Stuttgart.

On Wednesday evening, however, Huntelaar broke off these negotiations, apparently because he was not satisfied with the salary on offer. On Thursday he will report for training with Real, who are disappointed at his return.

According to Marca Thursday, 'he (Huntelaar) is becoming a problem.'

London clubs Arsenal and Tottenham are rumoured to be interested in him, though Real have so far received no concrete offers from them.
