His results made him speak for himself finishing better than his teammates Vettel at the end of his first season not with much point difference but still he announced himself that season and in the next one Vettel was poorly underperformed due that he was told to be let go at the start of the season.
It's not going to be 100 percent the same because Toto Wolf is not Mattia Benotto and Vettel is not as cool with things as Hamilton so again Russel need to make results that speaks for itself, and maybe Hamilton gets in his mind that this is the end of the road for him and time to let someone else get to the spotlight.
All of these depend on how Hamilton Performs in the coming days. Because if Hamilton is in his prime and he keeps doing better than Russell, I don't see any chance Russell gets to be the main man. But if Russell can prove himself worthy that he can be better than Hamilton, well we are gonna be up for an insane competition in between the two.
I somehow fear that if Russel gets the momentum, he may be able to outperform Lewis in some races, thus potentially creating a tension between the two. This also kinda reminds me on how Lewis and Nico started as friends but ended up as rivals until Nico's retirement. Though while the idea might be far-fetched, there is still that possibility of that situation happening again.
