Felix Magath is refusing to panic despite Schalke's poor start to the season and Manuel Neuer's revelation that he is considering leaving.
The Royal Blues have won just one of their first seven Bundesliga matches and find themselves second from the bottom of the table.
After Saturday's 2-1 defeat to Nurnberg, Germany number one Neuer admitted to Sky television that he is "not happy at Schalke" and that he is uncertain about whether he will stay until the end of his contract in 2012.
Those remarks have not alarmed Magath, however.
"Who should he be happy?" he said on Austria's Servus TV programme. "Nobody can be happy with the current situation.
"However, that does not mean I should doubt everything."
Magath signed 14 new players in the summer and released 15, and claims he made such a drastic change to satisfy Neuer.
"My argument is that I have to offer players like Neuer European football and that is why we started this revolution," added Magath.
"We did it so that we could find arguments to keep hold of somebody like Manuel Neuer.
"Everybody knows that such a revolution is problematic and even I don't know how long it will last."
Schalke face Stuttgart in their next match after the international break.
