Messi seems to be going to Beckham's American club, but he went to Saudi Arabia and apparently did not like something if he chose the American championship.
Someone jokingly said that "Messi might be a good footballer but he's not a good businessman". I don't really agree with this statement. We know how wealthy the Arabs are and that might have been ready to break the bank to bring Messi to Saudi Arabia but I don't think the offer was as juicy as what Inter Miami presented. Apart from the monetary package been given to Messi, the contract also has a clause for him to buy the club in the future if he chooses.
Well, if there is an option in the contract to buy a share in the club, it makes sense.
The American market is huge and could be worth more than the Sheikhs, but given Ronaldo's contract, maybe Messi could earn around 1 billion in Saudi Arabia. Given his age he could play 3-4 years, which is at least 200 million a year, plus probably bonuses, advertising contracts and 1 billion is quite a modest amount for him.
But he is closer to home and family in America and probably expects to take part in the World Cup in 2026, which will be held there.
