The budget for to buy these 2 players is about 200M.
Coutinho has made a statement that he wants to play in Barcelona, but Liverpool have also made a statement that the club will not sell Coutinho. Coutinho's transfer saga is very complicated. I do not know, but I think there will be an internal problem in Liverpool. Disharmony will occur.
Barcelona are not ready to sell Neymar until they are tempted by the money offered by Paris. Money can change a person's mind, that's what happened to Barcelona. Coutinho could have been released by Liverpool if there is an offer according to Liverpool match. The last offer from Barcelona is very big, but the money includes some conditions, as if Coutinho could win the trophy for barcelona and if Coutinho get BallonD'or. Unreasonable bids from teams that just made very much money.
