Burnley's pursuit of Borussia Dortmund defender Soumaila Coulibaly has hit a hitch that could rule the defender out of a move.
Vincent Kompany's newly-promoted Premier League hopefuls were aiming to sign-off a transfer for the highly-rated youngster and had agreed to complete a deal.
Initial terms had seen Burnley accept an initial loan that would also include a £15million obligation to buy at the end of that period.
The 19-year-old had completed his medical with last season's Championship victors, however, there is now a fear that the deal may fall through as pre-season preparations ramp up.
