The offer from the Saudi club is the only one Messi has received so far, the source added. Argentine media have reported that the offer is worth around $400 million a year.
The 35-year-old Messi has also been linked in the media with a move back to boyhood club Barcelona, with the United States’ Major League Soccer club Inter Miami also being touted as a possible destination.
He was suspended by his current club Paris St Germain at the start of the week after making an unauthorised trip to Saudi Arabia, French sports daily L’Equipe reported on Tuesday, adding that PSG had decided against exercising an option to renew his contract for a third season.
Messi is a Saudi ambassador for tourism and his long-time rival, Cristiano Ronaldo, signed for Saudi club Al Nassr in December in a deal reported to be worth around $220 million per year.
