Schalke have yet to open contract extension talks with Kevin-Prince Boateng as he remains tied to the club until 2016.
It was initially suggested that the Ghana international had penned a four-year deal upon his arrival from AC Milan in 2013.
Schalke, though, say the agreement was for three years with the option for a further 12 months.
That clause is yet to be explored, along with possible fresh terms, as Boateng has offered no indication that he is unhappy in Germany.
Chairman of Schalkeââ¬â¢s supervisory board Clemens Tonnies toldà BILD: ââ¬ÅKevin-Prince Boateng has a contract with our club that lasts three years.
ââ¬ÅThis deal has an option. The contract option implies that the deal will be automatically extended by one campaign if he plays a certain amount of first team games for Schalke.
ââ¬ÅThere are currently no talks on a new agreement between Kevin-Prince Boateng and Schalke. Every party has agreed on that.ââ¬
