Mainz insist that young teenage striker Andre Schurrle is not going to Manchester United or Bayern Munich.
Mainz's general manager Christian Heidel has reminded Schurrle's suitors that he is under contract beyond the end of this season.
"The transfer window is shut - that's a fact and no Bayern Munich or Manchester United can change that," he told BILD.
"We have not had any enquiries from those clubs and we have a contract (with Schurrle) so we are extremely relaxed about this."
