The Greens have offered Schildenfeld a new three-year deal but it is unsure whether the Croatian defender will commit his future to the club.
Schildenfeld has been approached by Dinamo Zagreb as well, an option which is really attractive for the Croatian defender.
“I'm open for a return. There are contacts but nothing has been finalised yet. I'm happy at Greece and Panathinaikos have offered me a new contract. But Dinamo will play in the Champions League and the opportunity is attractive. I won't to sort it out sooner than later. If Panathinaikos play in the qualification round of the Champions League I don't know what will happen,” Schildenfeld underlined.
