Hello Ian and thanks for getting us started :wave:
This could be an interesting weekend. I read that most teams felt the Mugello test was always going to be a bit of a waste because the track doesn't resemble anything like the tracks in the race calendar. I suppose they would just have tried out new bits on a back-to-back comparsion to check whether the effects were as predicted from the windtunnel and CFD.
As for Maaark :lol: (even JB calls him that) RB would be foolish to not re-sign him for 1 more year IMO. There's no way, bar any miracles in the middle of the year, that the new boys at TR will be able to fill his shoes any better. If they don't re-sign him then he could easily step into the Ferrari and they would be up a certain creek.
As for the GP, I read that Sunday has a chance of rain and temperatures will drop. Clearly that means that tyre performance will change between now and then, so whatever they do now will be quite different on the day. This could really mess up the McLarens in particular.
Renault/Lotus still look good but, as you are only as good as your last race, Vettel should be favourite at this stage...?
