The Frenchman lasted just 12 races before being ousted for Alex Albon over the summer break, having scored no podiums and only two top five finishes. Team-mate Max Verstappen did not finish outside of the top five until after the season's intermission.
Albon also could not perform to a level good enough to secure a long-term seat, and was swiftly replaced by Sergio Perez for 2021.
Now, the difficulties of the second Red Bull seat are affecting Perez, who has endured a torrid time of late in 2024.
The Mexican has averaged just over half of Verstappen's points each season, but his distance from the champion has become a serious threat to Red Bull's constructors' championship ambitions as rivals close in.
Marko is also the head of Red Bull's driver programme, meaning he is constantly weighing up replacements by overseeing dozens of pretenders to Verstappen's crown.
"[Arvid] Lindblad is only 16 years old. So it’s difficult to say but you saw the race at Silverstone, the [F3] Feature Race where he had enormous pressure from Mini [who is] in his second year and two years older with far more experience. He held him off and in the end, Mini cooked his tyres trying to catch him.
“For his age, he’s very mature and a lot of confidence like Liam Lawson. It might be the best thing to give them first a year at VCARB and then move up to Red Bull Racing.
"But they have, of course, to get more ready and they can’t go straight away and say we will beat Max," he added. "That was a mistake, for example, Pierre Gasly thought he was as good as Max."
Gasly came into Red Bull off the back of a strong season at Toro Rosso, and would have hoped to emulate Verstappen's stellar start to life at Red Bull.
