Vini is an excellent player. If he can maintain his fitness, he will become Real Madrid's main striker in the future. But Vini needs to be calmer and more modest. Vinny is a bit fierce. He reacted badly to the referee's decision. Such behavior should be avoided. He needs to be more calm. Also, Vini is often a victim of racism. I don't know why Vini gets attacked every time even though Real Madrid has a lot of black players. Vini may also have some personality issues. But Vini is still young, maybe that's why his nature is a bit fierce.
I am not sure that he will become the main striker as he is still a very typical wing player. Ronaldo was also a wing player but he was more directing his game towards the goal and the centre in many situations. Vinicius Junior isn't going straight into the centre as often as Ronaldo used to do it for Real Madrid. But Vinicius Junior doesn't even have to do it if Real Madrid now finds a strong replacement player for Benzema. He can then focus on his left wing position and pose a threat to their opponents from there.
As long as Ronaldo was in the Madrid squad, we never saw a better performance than Benzema. Ronaldo was the main player in Madrid. And the coach used to make his match strategy around Ronaldo. But after Ronaldo left the team, we saw how disruptive Benzema is. Real Madrid's squad has depended solely on Benzema's performances for the past few seasons. Now Benzema has left the team. Vini must perform well. Pressure will increase on Vini. Now Vini has to prove his mettle. He has enough chances to get himself on the list of legendary players of Real Madrid. But we don't know if he will succeed.
That's true but both Ronaldo and Benzema had quite a bit more of that striking quality. Vinicius Junior is good at it, but he is probably not a player who scores 30 goals and more per season. But Real Madrid will need that player once more.
Although I would say that Vinicius Junior has scored a couple of highly important goals and very crucial matches and he is still very young. I am not convinced he will score 3o goals and more, but he is extremely important to the team as he can hardly be stopped when he is at full speed.
