Southampton are ready to use goalkeeper Fraser Forster to lure in French midfielder Olivier Ntcham from Celtic.
Saints stopper Forster can return to the Scottish champions after a career-saving loan spell last season - however, they want something in return.
They are interested in a deal that would see them acquire 24-year-old midfielder Ntcham as part of a deal with Forster heading back up North, according to the Sun.
A potential factor that could hinder Southampton's chances of the switch could be Forster's contract, with Celtic having to agree to paying more than the £15,000-per-week they had to when they loaned the keeper.
