The thing with Russell is that he’s so consistent so if he has the car he’s got a real chance. But then you have to factor in the pressure which we haven’t really seen him have yet as he’s not been competing for the championship. He has had pressure in different ways but it’s not the same.Russell for me could be a bit of a dark horse for the title right now, but if Mercedes are on it from the off this time, I think he might become favourite if he can keep up form as I think he seems pretty confident all the time.
Hoping Hamilton can get to grips with these regs, but still don't have much confidence in the team and I don't think he or Leclerc do either.
I've heard about the loopholes too, and there's a meeting to clarify one of the rules around it, so if there's any big advantage those teams have found, the FIA may introduce something to counter it but we'll soon find out if it has any affect.
For what it’s worth he is currently second favourite behind Verstappen with the bookies but who really knows at this stage.
Will be interesting to see what leaks out from the first test as it is technically behind closed doors with no media but no doubt stuff will come out to give a bit of an idea how it’s shaping up.
