Sergio Perez has sparked rumours over his future at Red Bull with a series of poor performances for Red Bull, missing out on Q3 at five consecutive race weekends.
However, while a series of names have been floated as a possible replacement for Perez, Dr Helmut Mark refused to comment as to who might take the Mexican’s place.
“He started 15th, so sixth is ok,” Marko told Austria’s Osterreich newspaper following the British Grand Prix.
“There no question that he is endangered, in any case,” Marko added.

The speculation around Perez comes after Red Bull’s junior team AlphaTauri axed Nyck de Vries after just ten races at the team, putting Daniel Ricciardo into the driving seat.
The Australian’s return to the grid comes just months after he was unceremoniously ditched by McLaren for Oscar Piastri.
“If we bring him back, will you be nice to me?” team boss Christian Horner told reporters prior to Ricciardo’s return.
While Ricciardo will now be in the AlphaTauri seat, speculation over other contenders for Perez’s drive have been highlighted, including Lando Norris who put on a stellar performance at Silverstone.
While Norris is locked into his contract with McLaren until 2025, his agent was spotted meeting with Marko on the side of the British Grand Prix.
Former F1 driver Ralf Schumacher claimed that Ricciardo is likely not in the running for a return to Red Bull Racing this year or next, with Perez staying firm in his seat.

“At the moment I’m still assuming Perez will be in the Red Bull next year,” Schumacher told Sky Deutschland.
“But if Alex Albon was free, which he isn’t, or if Ricciardo can show his class again, things could get tight for him (Perez).
“But he has a contract and therefore I can’t really imagine a separation.”
