Just two races into a comeback from a broken wrist, the Aussie is making an impression within the Red Bull camp as the Mexican continues to struggle even with the adoring home fanbase behind him at the Autodromo Hermanos Rodriguez.
Although he has a 39-point cushion ahead of Lewis Hamilton after the Briton's disqualification in Austin last week, the pressure is now ramping up on Perez to secure second place in the drivers’ championship and his team's first ever 1-2 finish.
Qualifying behind Ricciardo will certainly not have done anything to quieten the voices who believe it's time for change in the second Red Bull seat.

Marko: He was unbelievable
Red Bull advisor Marko has done nothing to ease the pressure on home favourite 'Checo' with his remarks in recent times, and the Austrian gushed over Ricciardo's display after he secured an unlikely P4 grid slot for Sunday's race.
“He was unbelievable. He really drove that car to the best of his abilities and made the most of it,” Marko told Sky Germany.
“It was a great comeback after his injury and something to look forward to for his future.”
