Filling the left-back slot is an early priority for the former England boss having taken over at the City Ground and The People suggest on Sunday that former Forest loanee Bertrand could be returning to the banks of the Trent very soon.
Chelsea will decide on the 21-year-old's future when he returns from the European Under-21 championships currently being held in Denmark, with Swansea City also keen on a deal.
Another former Forest loanee left-back could also be available as Paul Konchesky looks to leave Liverpool. New Fulham manager Martin Jol has decided not to pursue a deal to sign the 29-year-old that had been in place before his arrival at Craven Cottage.
