Speaking with Sky Sports F1, the 2016 world champion reflected on the subject and said:
"I would say it's the first time, for me, to say that Oscar Piastri is now the big favourite to win the championship this year. I've never said that so far. In fact, I was always more on Lando's side. I was like, he's going to clean things up and just have that little edge and speed, and he's going to bring it home.
"But Oscar is just so strong. He's just always delivering zero mistakes. I've seen one mistake from him in the last two years in the most horrible conditions in Melbourne [in this year's Australian Grand Prix], and that's it. He's just always there. So for me now, the big favourite is Oscar Piastri."
The seven-time F1 race winner has a lead of 22 points over Norris after 10 races and two Sprints in the 2025 season.
