When this transfer took place Mbappe no longer attracts so much attention, instead they often start writing about how clubs from Saudi Arabia want to buy Vinicius, and perhaps this attracts so much attention because he has a clause of $1billion in his contract, but they are ready to pay it, and if it is true that they offered Vinicius a contract for €350m per year, this is a huge amount of money, it is hard to believe that a footballer can earn such money in one year. Maybe this is not true information, but I see that many different publications wrote about it today.
100% I am sure that Vincius rejected the offer, no matter how much the Saudi Arabian club spends to woo Vinicius it will not work. It seems that the Saudi Arabian club is overestimating a young player like Vinicius, a brilliant career in Europe, a candidate for the Ballon d'Or, Madrid proud striker and having a special place that can never be replaced in the main squad makes Vinicius a strong reason not to leave Europe too early. Moreover Vinicius is not a player who is hungry for money, his salary is more than enough in Madrid and all the club's existence. So don't expect him to go to the Saudi Arabian club.
