Crystal Palace are reported to be showing an interest in Toulouse defender Issa Diop ahead of a potential summer swoop.
Eagles boss Alan Pardew is looking to inject some youth into his defence as both Brede Hangekabd and Damien Delaney are the wrong side of 30, while reports also suggest Scott Dann could be on the move to Chelsea in the summer.
Diop is just 19 but has already broken into the Toulouse first-team and has caught the eye with some impressive performances for the French outfit.
Palace scouts are reported to have been checking him out over the past few months, leading to suggestions Pardew could make a move when the window re-opens.
Palace would face competition for his signature though as Premier League rivals Everton are also said to be showing a keen interest.
