While the Mexican has never overtaken his two-time defending champion team-mate Max Verstappen in the standings this year, he closed to six points after winning the Azerbaijan Grand Prix in late April.
But his form leading into the summer break has been dogged by a run of five consecutive failures to progress into Q3.
This has forced him to fightback in the races although, in the fastest car in 2023, he has not finished second to Verstappen in a full grand prix since the fifth round in Miami.
Speaking exclusively to Autosport sister title Motorsport-Total.com, Marko said this rough patch had allowed Perez to wake up from his title “dream” and this realisation will now enable him to focus on raising his performance.
The Austrian also reasserted Red Bull team principal Christian Horner’s assurances that Perez’s seat is not under threat as long as he sits second in the drivers’ championship.
Marko said: “We have a contract with Perez until the end of 2024. He is second in the world championship. What need do we have to take action?
“He has now woken up from his world championship dream. Maybe that will help him to focus again on delivering the best possible performance."
Marko added that Verstappen remained underrated for his intelligence and that his overall level meant it was “not possible” for Perez to ever surpass him in the championship.
"Max is underestimated,” said Marko. “He is an exceptional driver. Just looking at the mental capacities he still has. He even noticed on the radio when my mobile rang! [in FP2 during the Spanish GP].
