Schalke are doing all they can to keep the in-demand Manuel Neuer out of the clutches of their rivals.
The highly-rated goalkeeper continues to be linked with a summer switch elsewhere, with Bayern Munich and Manchester United reported to be monitoring his situation.
Schalke, though, have maintained throughout a season full of speculation that they have no intention of parting with the Germany international.
That remains their stance, with it their ambition to get the 25-year-old tied down on fresh terms.
Reports in Germany suggest Schalke have already put a new deal to Neuer, with the terms on offer intended to tie him down until 2014.
Chairman of the board of directors Clemens Tonnies has refused to deny or confirm the contract talk, but admits the club are doing their utmost to retain the services of a man who has played a leading role in Schalke's run through to the semi-finals of this season's UEFA Champions League, where they face United.
"Manuel Neuer is the main face of Schalke," he told BILD.
"We are going to do everything to ensure that he stays on.
"I have told him: 'Manu, your mission at this club is not yet complete. You will be able to achieve a whole lot more staying at Schalke'.
"He was extremely thoughtful after that."
