Mercedes got a huge jump on everyone, especially on engine development, in 2020. Ferrari, Honda and Renault will have bridged part of the gap by next season. I still think it'll be Mercedes, and therefore Hamilton, that wins. But I think, and hope, it'll be much closer next season.
I agree I would like the Ferraris to do better than last season but still it looks like the Mercedes are the favourites for the title and Lewis to be the king of F1
Lewis Hamilton is the obvious choice but Sergio Perez and Max Verstappen is a good shout in Red Bull Honda so is Daniel Ricciardo in McLaren Mercedes so is Sebastian Vettel in Aston Martin Mercedes and not forgetting the wild card entry of Fernando Alonso. It's going to be an exciting season so many to drivers to choose from. I hope it will be a lot closer Championship battle this season.
It will take a monumental screw up from Mercedes to not win both titles again. People still don't take on board the fact that Ferrari have too much in fighting and shoot themselves in the foot when blame is to be handed out and don't seem to know what they are doing during the race. Their own incompetence seems to hold them back. Sainz won't take a back seat role either so expect fireworks from that pair. Red Bull always show "promise" in testing only to realise that they are a second off the pace at the first race.... spend the season catching up and by the time Horner can announce " We gave the Merc boys a proper fight in that race" the title is long gone and they are still developing their car. The rest will be in the usual 1.0 - 1.5 Seconds off the pace. All while this is happening Mercedes have shifted focus onto the new car half way through the current season again.
Everyone makes improvements to their car over the winter. It's naive to say that Ferrari/Mclaren/Aston Martin/Red Bull have all made improvements to their cars and expect Mercedes to sit still. Remember the races looked closer in the second half of last season because Mercedes didnt bring any new developments to the car after Spa.
But you should know that the cars might be better than last seasons because improvements and all drivers can win championship except for the worst drivers
