The 21-year-old was a star for Germany at the 2010 World Cup finals in South Africa as he took his team to the semi-finals and was also nominated for the Golden Ball award. Oezil has just 12 months left on his current contract with Werder and has been linked with a number of clubs, including Barcelona, Real Madrid and Manchester United.
On Friday Madrid's sporting director Jorge Valdano conceded that they had made an offer for the 21-year-old which his Werder counterpart Klaus Allofs dismissed as not being "worth a negotiation". However, Oezil has now expressed his frustration at Werder turning down Madrid's bid for him and has indicated that he would love to join the former Spanish and European champions this summer.
"When you have such an opportunity like this, then you want to take it," Oezil is quoted as saying by Sky Sports after Werder's 4-0 win against Ahlen in the DFB-Pokal on Saturday. "It is any footballer's dream to play for the biggest teams in Europe."
The youngster also admitted that he found out about Madrid's offer for him only on television on Friday night during los Blancos' match against Bayern Munich and said that he will now talk to his club about it.
"I was very sad about that," he said. "I have said that to [director of sport] Mr [Klaus] Allofs."
With just a year left on Oezil's current contract, Werder could be forced to sell him this summer as they avoid running the risk of losing him for free at the end of 2010-11.
