Crystal Palace are trying to sign Charlton winger Ademola Lookman.
The South London Press understands the Eagles are ready to loan Sullay Kaikai to sweeten the deal.
But Brentford and Derby are also interested in taking Kaikai on a temporary basis – and the talented attacker is thought to prefer a move to the Bees.
Lookman has also been the subject of interest from Derby last week but there was always likely to be Premier League takers as the window ticked into its final hours.
The 18-year-old will cost around £4million.
Palace made at least one enquiry for Lookman last season, but Charlton rebuffed any talk of an exit while they fought against relegation from the Championship.
