Crystal Palace are close to agreeing a deal for Swansea City midfielder Flynn Downes in a move that is likely to see Joe Allen rejoin the Welsh club.
Championship Swansea are now poised to make a handsome profit on the former England Under-20s player.
His departure will allow Swansea boss Russell Martin to sign Wales international Allen.
The 32-year-old is a free agent after turning down a new contract at Stoke City this summer and is understood to be keen on a return to his homeland.
Allen, from Pembrokeshire, came through Swansea's youth ranks to make 150 senior appearances before leaving for Liverpool in a £15m deal in 2012.
