Schalke fans chanted "Joachim open your eyes," with the Germany coach in the stands for the match against Leverkusen, while Schalke coach Felix Magath urged Low to think again.
"Sometimes as a coach you have to take back certain decisions and change them," Magath told German DSF television's sports show on Sunday.
"It is always about how good the team can play and a coach you have to put yourself behind that."
"Essentially the coach brought this on himself and now Kuranyi is the best striker in the league."
"Kuranyi is a very good player and normally an international," Leverkusen coach Jupp Heynckes told reporters.
"I think Low should reconsider because we are not that strong up front especially if you look at how some other international strikers are playing at the moment."
"I still have hope. I am in the best form of my career but it is not up to me," he told reporters after the win against Leverkusen. "Only one man can change that and I will work for so long until he does change it," he said.
