The three-time champion was then dismayed to see Ferrari's Charles Leclerc overtake him at the pit exit, initially believing he had been undercut by the Ferrari.
"I just don't get it, why we let him undercut us by so far?! It's just so stupid," he proclaimed.
However, Leclerc had not stopped yet and had not undercut Verstappen. The Monegasque driver was on old tyres, and Verstappen easily passed him.
Verstappen's radio rants
Despite this being a mix-up in communications, it does add to the Dutchman's long list of radio rants at his race engineer Gianpiero Lambiase.
At the Hungarian GP, Verstappen was called 'childish' by Lambiase following an afternoon of X-rated rants from the Dutchman, while his frustrations over Red Bull's performance struggles have begun to show in recent races.
The Dutchman would have been thrilled to find out that Leclerc had not pitted, but continued to be frustrated by his inability to catch championship rival Norris.
