Hamilton will be leaving Mercedes at the end of this season, where he will join Ferrari for 2025 and beyond.
His replacement at the team is yet to be announced, with various drivers originally tipped for the seat.
Wolff has been frank in his desire to see Max Verstappen race with the team, however has since ruled out a move for 2025 suggesting they had settled on their line-up.
Mercedes junior driver Kimi Antonelli is expected to drive with the team next year, after impressing in various feeder series championships and for tests with the team.
The Italian bypassed Formula 3 to enter the Formula 2 championship this season, where he has achieved a sprint race victory at Silverstone and a feature win in Hungary.
Earlier during the Dutch GP weekend, Wolff seemed to let slip that it would be Russell and Antonelli driving alongside each other next season, and has since revealed a further promotion for the 18-year-old.
Wolff has now confirmed that Antonelli will compete in FP1 at his home grand prix at Monza next weekend.
The Mercedes boss has described the promotion as an ‘emotional moment’ as Antonelli makes his debut in an F1 session.
