During his career he grew up at PSG and everyone knows him thanks to his expertise in leading this team for many years. But unfortunately his age continues to increase and in fact his performance is still good enough to be at PSG. However, no one knows the future and sometimes it comes faster than expected if in the end he chooses to leave PSG.
An offer from a Saudi pro league team will certainly be difficult to refuse, especially since Marquinhos is so full of titles and experience from his time at PSG that even if he leaves, the club won't be able to hold him back any longer. The rest is that PSG must be prepared to look for other alternative players to fill the central defender position that he will leave and I think if Al-Ittihad are interested in signing him then they must quickly provide a proposal.
30 years old Brazilian and PSG centre back who spend his careers 11 years here at the PSG is not well famous but now having under radar of Al Ittihad as they are trying to fix their problems which hurt them in last season, and they were not able to stay at the top of Saudi League with most chance we will have this transfer because now PSG is also trying to have new blood which helps them for having better results in all competitions he was one of the highest paid player under 20 at the time of this transfer from Roma.
Offer is surely going to be considered by the PSG Management because now having new coach at the both clubs and trying to bring improved things going to be helpful for them having good amount into their wallet after selling Marquinhos who is captain but not well favored right now due to having changes at this club under Luis Enrique.
