Marquinhos wants to leave too (surely no-one has forgotten about Marquinhos favoriting a tweet about his move to Barca?), but it's not because the player wants to leave that he'll be sold.
Roma's president said Benatia won't be sold for less than 61M, of course that's an exaggeration, but he certainly will be more expensive than 40M too.
But since then and we have no proof he wants to leave beside that tweeter fav and Catalan newspapers:
- Marquinhos gave an interview to TF1 in which he said he has no problem. That he is a PSG player.
- Laurent Blanc was asked if marquinhos asked him a ticket to leave, he replied Marquinhos did not.
Now if you don't know Laurent Blanc, you could think he lies, but if you know him a bit, you know he doesn't since that when it's unclear, he's vague on purpose.
Check the podcast i posted. he's very clear about marquinhos, and super vague about Lavezzi. Just like he always is. When he's sure of something, he says it. When he doesn't want to reply, he's vague.
