I'm extremely disappointed with the outcome of Monza. IMO - the team massively underperformed.
lack of coordination and control over the tow situation during qualifying. Seemed they were just a bit too cocky with their supposed pace advantage vs. RedBull.
Wrong tire for the sprint. Starting on softs and not being vulnerable to the quick starters seemed like a no-brainer, especially for Hamilton starting on the dirty side. With only 18 laps to cover, it also seemed rather logical that the tire could last the duration on lighter cars.
Starting on the hard tire for the race was bang on and a brilliant choice.
Biggest strategic blunder; Why did they bring in Hamilton so early? Yes, I get that the situation fell into their lap with Verstappen having an extremely slow stop, but at the point they brought Lewis in, it seemed they had more time to spare with both Norris and Verstappen being held up by, I think, Stroll. Also, with Verstappen behind Norris in a potentially slower car, one would have thought that Hamilton could still not lose too much time on his alternative strategy...
I just didn't get the point of stopping that early. Not going to start on that slow stop - I mean, Mercedes isn't known to be extremely good at pitstops, but on the one day it was as important as ever, they stuff it up...
