However, Red Bull's dominance has started to diminish in 2024, leading to rumours surrounding Verstappen's long-term future with the Milton Keynes squad.
If Red Bull’s performance continues to spiral downwards, Verstappen could be tempted to join another team, which Ralf Schumacher believes would leave current Mercedes star George Russell's seat at risk.
"If Max Verstappen really decides to leave Red Bull, I can imagine that there will be a seat for him at Mercedes,” he told Sky Germany.
"Then it could be rather bad for George Russell. He is – or was – a super talent, but he also makes a lot of mistakes.
"If a world champion is then on the market, I can imagine that George Russell’s job could also be in jeopardy."
F1 reporter Christian Menath also believes Audi could play an important role in determining whether Russell departs Mercedes, particularly if they are unable to lure Sainz and still want an elite driver in their team for 2026.
"If Carlos Sainz doesn’t come [to Audi], then it could be really only a temporary solution, because in 2026 the driver market carousel turns again," Menath said on the Motorsport-Magazine YouTube channel.
"George Russell and others may be on the market. You don’t want to spoil that with a [Valtteri] Bottas or whoever.
"There will most likely be only a short interim solution."
