Schalke’s sporting director has insisted the club has done all it can to try and keep star midfielder Leon Goretzka.
The 22-year-old has attracted interest from some of Europe’s top clubs following a stellar season for the Royal Blues in which he scored eight times in 41 appearances.
Arsenal, Liverpool, Manchester United, Barcelona, Bayern Munich and Juventus have all indicated their interest.
However, sporting director Christian Heidel has insisted that he is hopeful that Schalke can tie the German international down to a new deal rather than lose him for nothing at the end of the season.
He told Sky Deutschland: “We are convinced that we have to have him stay here without putting pressure.
“We are trying to convince him, even in the economic aspect. We’ve made the most of possible efforts, we cannot do more.”
