Why do you say he will never reach the level of a Schumacher, Alonso or a Hamilton? These three people are indeed seniors in F1 but that does not mean that Verstappen will not reach their level, it just takes time for Verstappen to reach or even pass their level. Verstappen has all the resources needed to reach the highest performance point of an F1 driver, and that's what keeps his performance stable. Even during the previous race he was in P15, but he still managed to reach P2 and that proves his determination to be the best. Moreover, it is not good to compare past F1 drivers with current ones, because everyone has their own time.
Right now I think he has all the possibilities to become as good as Schumi and I think he is already better than Hamilton,in the 2021 season where car were almost the same it was only Verstappen bravery that brought him the title no matter that it were contested in the final race,I am talking about all season long,Mercedes were slightly better at that season and yet he manage to win so by doing it he has increased his self confidence to another level as shown in 2022 where he won easily the title.Now in 2023 let's see how it goes but he surely look posed to become 3 times World Champion which immediately puts him a step ahead of Alonso.
