Blues chiefs intend to try again at the end of the season and Bayer now must decide whether to cash in, or risk losing a massive €10 million off his sales' price next summer.
Kicker says Schurrle's current €25 million buyout clause stands for the reminder of this year before it drops to €15 million for the summer of 2014.
Increasing the pressure is Schurrle's former club, Mainz, are due 30 per cent of any sell-on fee over €10 million.
