Werder Bremen's Croatia striker Ivan Klasnic wants his future to be decided before Euro 2008, amid reports of bids from Besiktas and Wigan.Klasnic is out of contract in the summer and negotiations over a new deal are set to commence after the final game of the season on Saturday.

However, according to Bild newspaper, Besiktas have stolen a march on Bremen by tempting the 28-year-old with a lucrative offer.

Wigan are also believed to be monitoring the situation regarding the frontman, who has returned to form after a kidney transplant last year.

"I want clarity before the European Championships," said Klasnic.

That leaves Bremen just a few days after next weekend to convince him to stay before he joins the Croatia squad for their Euro 2008 preparations.
