Schalke are in talks with Chelsea over bringing defender Baba Rahman back to Gelsenkirchen on loan.
The Ghanaian full-back moved to the Bundesliga 12 months ago on what was supposed to be a season-long stint until a serious knee injury while playing at the African Nations Cup in January brought an early end to his campaign.
His ongoing recovery will be a factor in any deal but Schalke remain keen on the 23-year-old, who made 20 appearances for the club in the first half of last campaign.
"We are in talks with the player, his advisor and Chelsea," said Schalke's sporting director Christian Heidel.
