Media reports claim that Crystal Palace are keeping tabs on Mamadou Sangare, who currently plays as a midfielder for Lens. The move is still in the early stages, but interest appears to be growing. Until a fee and conditions are finalised, the deal remains vulnerable to disruption - especially if Tottenham, Chelsea and Man Utd decide to make a formal offer of their own in the coming days. Reports suggest Crystal Palace are monitoring Christian Norgaard and Charlie Cresswell whereas Lens have not been associated with other players at this stage. Want to see how the story develops?
