Barca have entered negotiations with Liverpool over a January deal for Coutinho.
And Don Balon says watching on nervously is Ousmane Dembele, who has just been given the all clear to resume playing after a September hamstring injury.
Dembele sees Coutinho's signing as a direct threat to his status, with the Frenchman yet to truly establish himself in coach Ernesto Valverde's plans. And with Coutinho to arrive for a €100m-plus transfer, Dembele cannot even rely on the €140m Barca have committed to pay Borussia Dortmund as reason for his selection.
Dembele has confessed to friends he's concerned - just as he prepares to return to action.
