"El Mundo" also state that for Barça to consider a transfer move for Neymar, his father would need to drop his legal battles with the club, something he won't consider doing at the moment.
He has lost his place in the side to Arturo Vidal and Ousmane Dembele now appear to be ahead of him in the pecking order.
Manchester United are reportedly "in talks" over a potential move which would cost in excess of £100m and the Evening Standard claims that Barca want Neymar back as a world-class addition to their ageing strike force.
According to Mundo Deportivo, United have contacted Coutinho's agents to ask about his situation and admit they would be "very interested" in signing him.
That's because Coutinho's £142 million deal contained a number of clauses.
Their displays have meant that Coutinho has been unable to nail down a position either in midfield or as part of the front three.
He's now played 34 at the time of writing, meaning the first payment has already been triggered - while Barca have already paid £4.4 million after qualifying for this season's Champions League and will do so again if they are in Europe's premier competition again next year as expected.
Finally, Barcelona would owe another £4.4 million if they win the Champions League this season.
