Valtteri Bottas has announced he will be "more selfish" in 2021.
"Valtteri has been in an unfortunate situation in recent years with short contracts," team boss Toto Wolff acknowledges.
"But he has handled the pressure well. He's a cool Finn - he can handle those things," he is quoted by the Finnish broadcaster MTV.
"The new rules will come into force in 2022 and that is why we need to monitor how things are progressing in the coming period," Wolff said.
"I am pleased with Valtteri and the engineers are happy with Valtteri. He deserves his place at Mercedes and the cooperation with Lewis works great."
Bottas, 31, insists that beating Hamilton to the world championship remains his target.
"You have to take it step by step," he is quoted by RTL. "I will ask for as much support and information from the team that I need. And maybe I will be a little more selfish.
"In some years I definitely put too much pressure on myself," Bottas added. "There were times when I got too much pressure from the outside, but also vice versa, when maybe there was not enough pressure on my part."
