German side Hamburg have denied receiving any offers for their Dutch playmaker Rafael van der Vaart and said he is not for sale anyway. "We will not release Van Der Vaart, everyone at the club is very firm on that," Horst Becker, president of the board of trustees told daily newspaper Hamburger Morgenpost on Monday. The 24-year-old midfielder has been linked with a move to Valencia for a reported 14 million euros. The talented midfielder has been also a top target for several European clubs including Spanish giants Real Madrid who could force a move in the next few days. Van Der Vaart signed for Hamburg in 2005, coming from Ajax, and is under contract until 2010. The Dutch ace has been in a splendid form as he led the tam to the third place of the table in 2006 and the seventh in 2007.
