Jordan went on to add that Verstappen's recent form is showing the true pace of their car: "We were all slagging off Perez, but maybe Perez and that car, that's the speed of the car. What Max is doing is what Max is able to do.
"Therefore to finish fifth, fourth and sixth or whatever... Jesus, it must be killing him at this stage."
Verstappen voiced his concerns about the car last week labelling it a 'monster' as the three-time world champion finished outside the top five in Monza.
If Red Bull are to defend both of their titles this year they'll need to get on top of the wind tunnel issues and identify the issue as soon as possible.
