So who should be extra careful come Zandvoort? Pourchaire?

I believe it was said that PIA suffered from floor/underbody damage, causing his pace to drop considerably compared to NOR. I don't even think the pit crew expected NOR to overtake PIA while he's still exiting the pit lane. And the laps after showed that PIA simply couldn't keep up and would've slowed NOR down if it hadn't worked out the way it did.
