Conor Gallagher has completed a medical at Crystal Palace ahead of a season-long loan at Selhurst Park - however the move is being delayed by contract talks in west London.
Chelsea are trying to tie down their 20-year-old star, who was the pick of the bunch from last season's loan group, due to him having less than two years on his current deal.
It is expected that a deal will be agreed for the season-long loan that will see Gallagher follow in Ruben Loftus-Cheek's footsteps, having had a year in South London before earning a permanent spot in the first-team squad.
