Nope, it isn`t just X post. It is post by Fabricio Romano. He is well known as football insider and often give us correct information before officials. Of course it is not 100% guarantee, but he is someone who can tell the truth.
PS. The same time he told just the part of the truth. No words how much Barcelona got from Messi.
Don't give Fabricio Romano too much credit, he can't be more than a sports journalist, he is still not Messi nor Barcelona, they are the ones who can guarantee those figures officially and I am happy you mentioned it similarly in the latter part. That was even by the way, the main gist of my post was that Messi earned what was agreed upon between him and Barca, no one forces the other here, so labelling him greedy or a destroyer is 100% out of place.
I don`t ready to give him too much credit, but the same time i can`t call him noname X user. He made good predictions lots of time. I wanted to say mostly about it. And of course no one knows what was between Messi and Barcelona without witnesses. And as i said, we see only Messi`s profit here. Without words about what Messi gave to Barcelona.
