Schalke are chasing Chelsea striker Bertrand Traore.
The Daily Mail says Traore is a target for Bundesliga side Schalke.
The Burkina Faso international has impressed on loan at Ajax this season where he scored 14 goals and helped the Dutch side reach the Europa League final.
They are interested in making his signing permanent. Sunderland have also asked about taking Traore on loan.
Chelsea want at least £17.5million for Traore, who is also being monitored by Ligue 1 club Lyon.
