Vini jr was over £40m when he joined Real Madrid at the age of 18, so it wouldn't be anything too insane.
Rodrygo to Real Madrid was €45M as well.
Both the Rodrygo and Vinicius deals were also agreed more than a year in advance and they moved after turning 18. Considering the inflation of the transfer market I'd say €45M in 2017-2018 money is at the very least equal or perhaps more compared to €60M five years later.
Very much doubt he’ll end up at Chelsea to be honest. He’ll have his pick of clubs.
Yeah it looks like this guy can go wherever he wants, but it also matters how each club is pitched to the player and his family.
It's being reported that Chelsea have pretty much promised to make him 'the face of the club' and slot him in the first team in a key role straight away at 18. I very much doubt he'd get the same treatment at Real Madrid, Barcelona or PSG where he'd be just a promising youngster in a team already full of superstar attackers.
I too think he'll most likely end up at one of Spanish top2 because for a young South American boy it can be very difficult to refuse the opportunity when those two come calling but I also wouldn't completely dismiss our chances at this point. Even if he joined us and signed a 5-6 year deal he'd still only be 23-24 at the end of it and assuming his career development goes about as well as he's being hyped he'll still have his pick of clubs then if he wants to go somewhere else.
