Neuer has been strongly linked with the likes of Manchester United and Bayern Munich in recent months.
“A year ago, we would maybe have had to think about a transfer in the situation we were in, but not now,” Magath told Kicker.
“We are now far better off financially and do not have to sell Manuel Neuer.”
Neuer’s current contract at Schalke is set to expire in the summer of 2012.
