Lewis Hamilton has said that Valtteri Bottas has "earned his place" at Mercedes.
Team boss Toto Wolff has indicated that, while happy with the Finn, he is in no rush to extend Bottas's deal into 2018.
Bottas's teammate, Hamilton, said in Baku: "I honestly think he has earned his place with us.
"He's doing a great job and he's going to keep developing. He's in his first year and has already won a grand prix. I think there's much more to come, he just needs to get the right opportunity."
Hamilton has also said that he is enjoying the atmosphere in the garage, following Nico Rosberg's retirement.
"[Bottas's] energy helps to create a great harmony in the team," said the Briton.
Hamilton and Bottas are currently second and third in the driver rankings respectively.
