German side Schalke 04 say the leave the final decision to have Ghana defender Baba Rahman at their club to Chelsea.
Schalke have sent a mail enquiring about the player who has been out of action for over a year with an injury.
Schalke chief Christian Heidel watched Rahman's game for the reserve side at the weekend and has been impressed with his recovery.
''Getting Baba depends a bit on Chelsea, maybe they want to make something else in the transfer market,'' Heidel told Reviersport.
''We do not have the pressure like he has to play tomorrow, so we are waiting quietly.''
Rahman who has fully recovered and is training with Chelsea has also been linked with Fiorentina and Newcastle United.
