Norris announced last week that he had committed his long-term future to McLaren, with a new contract that takes him beyond the 2026 season.
Speaking about the reasons for sticking to his current squad, the British driver explained that he felt there was no better place for him to achieve his target of the world title.
Although he has yet to deliver a victory for McLaren, his team boss has no doubts about just how good the youngster is and how he stacks up against some of F1's greatest.
Stella, having worked with the likes of Fernando Alonso, Kimi Raikkonen and Michael Schumacher, sees Norris on a similar career trajectory.
"Lando definitely stands together with them," explained Stella.
"It is the same category, the same kind of world championship material, the underlying talent, the mindset, the work ethos. It's all ready to go.
"But at the same time, when you think about champions, there is a characteristic of champion in that they only get better.
"Real champions, they seem to just improve year by year.
