I feel that I’m at my peak, and I still feel that I’m getting stronger as a driver. But right now, I’ve waited so long that I want to make sure that it’s right. It’s got to be right for the team, it’s got to be right for myself, it’s got to all make sense – the duration has to be right both ways."So, it’s not as simple as just saying, ‘Are you happy with what you’re being paid?’ That’s a very small factor of it. You’ve got to have faith in the performance in the future as well, because I would pay to be a World Champion, I would pay to fight for a World Championship, and that’s where I am right now. That is the priority for me.”George Russell has been with Mercedes since his junior days and was promoted to the senior team at the start of the 2022 season, and has gone on to become their lead driver this year.
