Whilst the Mexican driver has helped Red Bull achieve two 1-2 finishes so far this season, his seat might still not be safe.
The 2023 season saw Perez criticised for failing to match the pace of Max Verstappen, with Lewis Hamilton nearly catching him for P2 in the championship.
Fernando Alonso has also been linked to a potential Red Bull drive, however one name in particular seems to be a favourite to join Verstappen.
Carlos Sainz has been praised by Christian Horner and now Helmut Marko, after an impressive start to the 2024 season.
The Spanish driver won the Australian GP, returning from surgery on his appendix only weeks before, outperforming teammate Charles Leclerc.
Discussing Sergio Perez’s seat with Sky Sports Germany, Marko also threw Sainz’s name into the discussion.
“Perez had his worst race last season here. Everything went wrong and now, you can see he can do it. You can see that it’s also about a seat for next season.
“We don’t usually talk about possible decisions but he’s been pushing towards the right direction. However, it is still too early for us to say. We still need some time before making a final decision.
“Sainz is currently in top form and you heard Leclerc’s radio, even he doesn’t know where the setback is coming from.
“Sainz made it to F1 through Red Bull and had a great year with Torro Rosso. Sainz is for sure a name you need to look out for.”
