The amount of the offer the Saudi club is offering to Lionel Messi is just staggering and I think it'll be tempting to Messi as well but I think Messi still wants to play in Europe for at least two more seasons before he can leave but considering the deal that's been placed on his table already he might want to change his mind about it.
Whatever might be the decision of Messi, I know that football faithfuls would want to see the greatest players of modern day football compete against each other once again before they call it a day on their illustrious careers.
