Stepping into a 105-time race winner's shows is no simple task, and established top tier drivers Max Verstappen and Carlos Sainz were touted as potential partners to George Russell.
However, more recently F2 and Mercedes Junior Team driver Kimi Antonelli has appeared to be on the verge of signing for the team, though Wolff has sent mixed messages so far at the Dutch Grand Prix.

With Antonelli in pole position to step into the vacant Mercedes car at just 18 years old, Wolff appeared to let slip that the lineup of the young Italian and Russell was set for 2025.
Speaking with Dutch media outlet De Telegraaf, Wolff said: "The two drivers in our car next year have our full support. I want to make it work with George and Kimi," prematurely unveiling Antonelli as the chosen replacement.
It was already reported that Antonelli would be announced at the upcoming Italian Grand Prix, with the youngster expected to take part in FP1 at Monza, as per motorsport.com.
However, speaking with Sky Germany after Friday practice at the Dutch Grand Prix, Wolff suggested that the Monza announcement may not materialise.
Mercedes F1 CEO Toto Wolff refused to say when an announcement could come
Pundit Peter Hardenacke asked when a decision would be made, given the recent announcements of Carlos Sainz and Jack Doohan's moves.
"Everyone knows what we’re doing. We’ll announce it shortly. Maybe we’ll take our time until Abu Dhabi [the final race of the season], but nobody is rushing."
Despite Monza seeming the perfect place to announce an Italian signing, Wolff refused to confirm that would be the case. Still, the confirmation of Antonelli at Mercedes seems a matter of when, not if.
