WYCOMBE want to sign QPR midfielder Tommy Doherty before the transfer window closes on August 31.
The midfielder was Wanderers' Player of the Year last season while on loan at Adams Park and Lambert is keen to get him back.
Rangers are still demanding a transfer fee for the former Northern Ireland international, who has a year left on his contract.
Blues boss Paul Lambert said: "It's certainly not dead yet."
Rangers are currently in the middle of a takeover and any deal could go right to the wire.
Lambert said: "The goalposts have changed a little, but I still want him and if we could do it before the deadline I would.
"He was brilliant when he was here before. I've spoken to John Gregory Rangers' boss a couple of times."
Doherty has only just returned to training after having an emergency appendix operation.
Lambert said: "Talks are ongoing. He's just getting back into training at QPR after his operation. That appendix problem was a disaster for him."
