Lando Norris said it will be "a big challenge" for himself and for McLaren to adapt when Oscar Piastri replaces Daniel Ricciardo at the end of the season.
The Brit will have a new team-mate in 2023 when Piastri links up with McLaren. Last year's F2 champion will be racing in Formula 1 for the first time, after quitting Alpine to defect to their midfield rivals.
The legal battle over his future has now been resolved, and he was officially announced as Ricciardo's replacement by the team on Friday. Speaking after qualifying seventh for the Dutch Grand Prix, Norris revealed his reaction to Sky Sports.
