According to Sport, Coutinho's move to Bayern, which relieves a big salary, can bring Neymar closer to Barca and prevent Gareth Bale to Bayern.
Bayern would pay Coutinho's €12m salary, giving Barcelona the financial power to fund Neymar's transfer.
Meanwhile, now that Bayern have already signed Coutinho, it is unlikely they will go to loan Bale from Real Madrid.
