Maybe they are saying the truth about winning their real power back now. We saw an example of it at the beginning of this season in the end. They were very promising. The only thing they need to do this time is to keep consistency. They need to work with better workers to have a season with minimum amount of problems. If we see them having durability issues again it would be a really big disappointment.
I don't think there are teams that can really keep up with Red Bull in the coming season. It has been tense for a while in the past, but that was mainly because Red Bull did not have the car technically in order. And at Ferrari, the problems seem to start after a few races. It was soon clear that Mercedes would not play any significant role in the championship, but I had expected some high placings from Lewis and a win here and there. What Verstappen has achieved is unprecedented when you look at the number of victories. A record he may never even break.
