Just looking at the long runs from the race, the Mclarens would probably have had enough race pace to scare Gasley in the other Red Bull if they weren't both suffering from damage - obviously they would have had a lot of traffic stopping them from getting up with him but that's very encouraging given the front end/tyre temp issues, it's evidently no real issue in the race now once they get the extra weight in the rear from the fuel.
If they can get on top of the front tyres when there's no fuel in the car for qualifying it'll be a fair step forwards.
