I understand it and i disagree.
And I don't see the point in selling marquinhos to buy benatia right after. Especially if it means buying Benatia for more than what we paid for marquinhos with a high chance that benatia wage will be greater than marquinhos'.
And again, it goes against your logic. You just said that "since it will be too late for other targets they will go for marquinhos", if it's too late as you say, it would mean benatia is already sold.
Or it doesn't make sense, if Benatia is not sold, why not offer Roma 70M yourself instead of offering 70M for marquinhos.
Barcelona should just understand it, it's dead. Blanc doesn't want to sell him, and Nasser was against it from the start. We have those informations from LeParisien and Radio Monte Carlo who asked it to them themselves, not from rumors from spain.
