Spa is already a lovely track in the calendar and there is more! On Saturday and Sunday both rain is expected. As far as I can see it is more likely during the sprint and race.
That change things a lot for predictions, but they are not always precise so I would wait to check weather again in few days.
I am giving more advantage to team McLaren in case there is rain this weekend.
I have a big feeling inside me there is still one more good win in Lewis, but the odds on betting don't really favor you to try it (too low). He has to be patient, wait for both McLaren to get into issue or technical problem etc and just compete based on that.
Maybe, he is not doing bad in last races this season, always hanging around top 6 drivers. but I think it is time for him to finally retire and allow younger drivers to compete.
