Obviously I don't know anything about this lad in particular but I was talking about deals like this on the Gnonto thread earlier: we have three established wing options + Ndiaye in a pinch so rather than blast 25m+ at Gnonto get in early on a young raw kid like this if we've spotted him and try to get the sort of bargain Newcastle or Leeds got buying Minteh or Gnonto rather than the big bucks they want selling them on.
Sign him relatively cheaply. Loan him to a Dutch club, let him score plenty and then we either bring him in or sell him at a tidy profit.
