This is what I am trying to explain to you. There are those of us who feel he has proven it - definitively - without question. So ask yourself, who should Sebastian be concerned with? Those who have stuck with him through thick and thin and appreciate his talent, or those throwing out a series of challenges for him to meet before they will recognize his talent? Especially when those challenges differ from person to person and some are just silly.
To be honest, both the fans and doubters are important. Remember not all doubters are ridiculous and not all fans are rational. I think we're looking at realistic fans and doubters as equally important and valid, some fans are pointlessly optimistic/deluded and the same is true of doubters, they won't accept anything - throwing out conspiracy theories etc. at every opportunity.
Saying that I think both are not important at all. Vettel should do things for himself, his team and his family. If he's happy to win races and championships but have half the fan base question his suitability in the top five of all-time then that's what he should do. My point is that there are certain things he needs to do to be considered 'the best' e.g. do a Schumacher going to Ferrari, do a Prost against world championship winning teammates.
Whether that's right is another matter but there are still doubts around Sebastian.
Early 2012, Red Bull struggling with rear stability - Webber just as quick if not quicker. In 2010 Webber was also quicker at points when the car wasn't to Seb's liking concerning engine mapping. Seb is a fantastic driver but only a deluded fanatic won't admit a lot of his success is due to Red Bull's rear stability and the engine mapping genius of Renault/Red Bull. Vettel is Mr. Ideal for the Red Bull, it's built towards his strengths.That shows that he has the qualities of a Schumacher or Alonso to get the team building towards him...very essential.
What some question is whether he can beat others when he's not in a Red Bull or whether he could beat another top driver in the Red Bull. Let's not forget, with Webber's height, driving style and age he's a long way away from optimal. Put Alonso in a Red Bull, slight of stature, smooth and in his prime, we could be experiencing the most intense rivalry ever.
For now Vettel should just be concerned with racking up the records. In my opinion 2015/2016 he needs to move away from Red Bull, get a new challenge, a new teammate and try to cement his legacy. You might be happy that Vettel is the best but I have a friend who's convinced Hamilton is the best F1 driver of all-time. Again, not all fans are rational.
When Vettel has driven as long as Alonso has, you can compare their careers (i.e., when they both retire). Hamilton and Vettel are both tremendous qualifiers - who would bother to argue that? With those two, "better" is meaningless.
It's impossible to know who's better in qualifying (between Vettel and Hamilton) but 'better' is important. Had Vettel been better he would have been on pole in Monaco and Hungary, making errors on both fast laps. Had Hamilton been better he would have been in a better position for the Monaco and Monza races. Both missed opportunities so improving and extracting everything is crucial.
Right, so when Vettel has driven as long as Schumi - done his 12 years - then we'll have this conversation. Until then, driving against Alonso or Hamilton or Raikkonen won't tell us much at all, imo.
I agree, probably best to wait.
