The British driver is out of contract with the German team at the end of the 2025 season, and despite his brilliant start to this year, he is yet to sign an extension with the former world champions.While appearing on the TalkSport Driving podcast, the former Ferrari driver said:“As a racing driver, it’s not an ideal situation. We all try and hide the fact that it affects you, we try not to be affected. I strongly believe that, like I did last year, you can still have a very strong season with all this noise going around your future and around your team, like it can be proved by what George is doing this year and what I did last year.""But at the same time, it’s not ideal. It’s noise for you. It’s noise for the team. It’s noise for your engineers, for your mechanics. Even though you can still have a very successful season, it’s not the ideal situation and it’s not what any driver wants.”George Russell and Carlos Sainz also share additional duties in the GPDA, with both being directors in the body after the latter joined at the start of the 2025 season.
