The 22-year-old is currently impressing while on loan with Belgium side Zulte Waregem, and his performances have not gone unnoticed, with a host of Premier League clubs said to be showing an interest.
Reports have already linked the midfielder with a £6million move to Liverpool and West Ham, but it is now claimed that only Stoke and Palace have made ‘concrete’ offers for the player.
Zulte are said to have first option to keep him on loan for another season, but that may be scuppered if Lille receive a firm offer for a permanent deal.
There has also been interest from the Bundesliga, but reports claim that Hoffenheim and Schalke have cooled their interest leaving Stoke and Palace to battle it out.
