I did saw this transfer update from Fabrizio Romano and I must say a $400M/year deal is quite a tempting offer from Al Hilal. When Al Nassr came for Ronaldo, I was among those that never thought he would accept the offer because his quality hasn't declined, but he did. With this kind of offer on the table for Messi, he might want to consider it, considering the fact that PSG is not interested in renewing his contract or what they are offering is not appealing to him. Though, Barca is still in the picture but I doubt if they are ready to offer close what Al Hilal is offering.
I agree with Joan Gaspart when they said Messi should stay in PSG even for a minute, he is a legend in Barcelona where he can be gt the respect he deserves while PSG they disrespect him all the time, in Barcelona, they love Messi however he can't get the money he can get in Asian and Arabian teams. I guess Barcelona will be his next and final destination.
