After winning three out of the last four races before Zandvoort, Toto Wolff's confidence in the team would have been sky-high.
However, after both of his drivers failed to finish in the top six at the Dutch GP, the Austrian appeared desperate to solve the newfound issues with the car before heading to Monza this weekend.
Speaking to media after the race, the Mercedes principal said: “We’ve had six podiums in a row and that doesn’t look like the car three weeks ago that was first and second, at least first on merit [after Russell was disqualified].
“You can’t really end up with a result like this without any major factor playing, and that’s something we need to analyse in the next few days until Monza.
“Was it a setup? Was it the track? What is it that we got wrong? Was it the floor that we put on the car? Was it all of this together?
“Hopefully we can sort it out for Monza and become competitive again, but the swing in performance from P1-P2 to P7-P8 there’s a biggie in there.
“It’s not something that was simply a setup decision in my opinion.”
Mercedes lie in fourth place in the constructors' championship, with Hamilton in sixth and Russell in eighth place in the drivers' standings.
