Mercedes team principal Toto Wolff says Sebastian Vettel “is someone you can never discount” when it comes to potentially replacing Lewis Hamilton next year, despite preparations ramping up for the team to test Formula 2 racer Andrea Kimi Antonelli.

Vettel spoke about being tempted by a potential return to Formula 1

earlier this week, and admitted he has held discussions with Wolff about multiple things relating to his future plans, but not necessarily the Mercedes vacancy. After Hamilton stated “I would love for Seb to come back and I think it would be an amazing option for the team,” Wolff said the four-time world champion can’t be ruled out.
