Vinicius Junior decides to stay as it seems which is not surprising news at all.

Of course he was going to decide like that at this young age. He is only 24 and he has lots of more trophies to win with Real Madrid in the future.
He was going to get an enormous offer from a Saudi team normally. They were rumoured to offer 300 million euros to Real Madrid as transfer fee and 200 million a year as a salary to the player. That's of course an insane offer.

But not enough to convince a player like this anyway. As far as I know he makes 25 million a year with bonuses now but not everything is money. Achieving successes in Europe is much more valuable than the successes in Saudi Arabia obviously.
Vini was robbed of Ballon D'or and will not leave Europe, because he still has the dreams to win Ballon D'or and more UCL trophies. Someone that can happily go to Saudi is an old player that gas achieved everything and needs somewhere to retire with fat pay. Vini career is just getting to the peak and it's only in Real Madrid that he can improve his performance and make record for himself. Going somewhere else, will make him not achieve this goal.
