Bundesliga side Schalke remain keen on re-signing Chelsea defender Abdul Rahman Baba .
Schalke sporting director Christian Heidel has hinted the Bundesliga club may look to sign the Ghana international on-loan in January.
Rahman was with Schalke on-loan last season before injury on international duty with Ghana cut short his deal in January.
The left-back is expected to be fully fit by January 1.
"Is Baba ready to help us in the second half of the season? You have to see," Heidel told Revier Sport.
