Checo will take some confidence into the race having ended a streak of five successive races without a Q3 appearance, but P9 isn't good enough given the machinery underneath him.
With Daniel Ricciardo punching in a P13 finish on his return to the sport in a much slower AlphaTauri, the pressure is on for Checo to execute a clean race on Sunday.
Podium aspirations for Perez
Speaking to Diego Mejia of Fox Sports MX after the qualifying session, Perez explained: "It was a very strange quali because we used all compounds and this made it more complicated,
"We even tried two different setups in Q3 to drop temperatures and this cost us.
"But we have a good car for the race tomorrow.”
Perez was then asked for his opinion on the Red Bull upgrade package, responding: "Complicated in this circuit. Definitely we’ll be doing better in faster circuits.”
The Mexican rounded off his interview by revealing his target for the Hungarian Grand Prix on Sunday.
When asked, he simply replied: "Podium, no doubt.”
