For Haaland and also for Mbappe, I agree that they are level. They played brilliantly at their club. Even Mbapppe also played very well when he brought his national team to the world cup. However, I'm not sure about Vini. You could say it's still too much for him if he's on the same level as Haaland and Mbappe.
Mbappe, Haaland and Venicius Junior are not the same three players, we can consider the three in three different levels due to performance dribbling and speed. Although Haaland can score regularly, he has not yet become a player like Mbappe. Mbappe has enough speed and finishing skills, but Haaland will definitely lag behind Mbappe. On the other hand, if we consider Venicius Jr.'s performance, we can clearly see his great dribbling skills. Venicius Jr. may not score many goals, but he is good enough to score goals. Mbappe can finish like Venicius Jr. but he can't finish like that. Considering all these things, these three players do not seem to me to be equal players.
