Wittmann mentioned: “We misplaced the place on P1 within the pitstops which is a little bit of a disgrace. This has been a little bit of a subject the entire season just about that the Mercs and the Ferrari have a bonus with the way in which they do their pitstops.
“Clearly it’s kind of arduous to swallow to lose the win like that, as a result of there’s clearly a mean time lack of 1.5-2 seconds roughly just about every pitstop to them and it was clearly the win decider, so on the finish I’m fairly pissed off.
