Mercedes boss Toto Wolff has said Valtteri Bottas has so far "exceeded expectations" since joining in the off-season from Williams.
The Finn secured his first-ever win in Formula 1 when holding off Sebastian Vettel in Sochi and has been on the podium in three other races, most recently in Canada.
Bottas is hoping to extend his stay at Mercedes beyond the end of the season and has clearly made a good first impression on the boss.
"Valtteri is in a strong position," said Wolff via the Mercedes official website.
"You would never think he joined the team very last minute over the winter and, after, seven Grands Prix, he has exceeded even our expectations.
"He’s been on pole, won a race and challenged Lewis on both Saturday and Sundays. For him, it’s now just about putting it all together."
