Schalke head coach Felix Magath is confident that he can persuade Germany goalkeeper Manuel Neuer to remain at the club beyond next summer.
The 24-year-old is out of contract at the end of next season and Neuer is reported to be a target for the likes of Manchester United and Bayern Munich.
Magath told Bild:"There is no doubt I am confident about keeping Manuel Neuer, plus the rest of our key players at our club, even though it looks like future revenue could become more difficult if we are not in any European competition next season.
"We have established the requirements to end up as champions of the Bundesliga in the next couple of seasons.
"Everyone knows that a world-class shot-stopper like Gianluigi Buffon once stayed at Juventus, even though they were a second-tier club for one season.
"I have an obligation to show Manuel Neuer that he has a good future at the club.
"Just looking at the current Bundesliga table, Manuel Neuer would not be playing in the Champions League with Bayern Munich next season."
