Chelsea have recently been linked with a move for Schurrle and after reportedly having an earlier offer turned down, the Blues are said to have returned with a €23million bid, with further add-ons based on appearances.
However, Leverkusen director Wolfgang Holzhauser insists the Germany international, who only joined the Bundesliga side at the start of last season, is not for sale at any price.
"The offer was worth over €20million," he told Kicker. "We do not want to talk anymore."
Leverkusen sporting director Rudi Voller also revealed one of the key reasons the club were refusing to do a deal for Schurrle was because they would be unable to find a suitable replacement at the right price.
"The players on the market are too expensive and we would have replaced [Schurrle] with a worse player who is overpriced," the former Germany international said.
"There is no alternative to our decision because we would not be able to get an adequate replacement. I have also discussed this with Andre."
Schurrle's performances for Leverkusen last season earned him a call-up to Joachim Low's Germany squad for Euro 2012, but he was limited to a bit-part role in Poland and Ukraine.
