Sane is expected back at Schalke on Wednesday after an extended break following his Euro 2016 campaign with Germany, with the German club valuing the winger at £40-million, according to SkySports.
The 20-year-old winger was outstanding in the Bundesliga last season scoring nine goals and registering seven assists from 42 appearances in all competitions.
