The Instagram post Rosberg is referring to is Hamilton’s message in response to the news of Bottas’ departure.
The seven-time world champion posted several photos of himself and Bottas throughout the years, along with the caption: “I’m immensely proud to have worked alongside Valtteri for the last five years.
“Together, we’ve been part of a team that has delivered four Constructors’ Championships, and we’ve motivated one another to keep pushing through the ups and the downs.
“He has been the best team-mate I’ve had the pleasure of working with. Your speed and resilience has been impressive but where you truly stand out to me is the human being you are and gentleman. You are greater than you know and I know there’s a bright future ahead for you.
“Thank you Valtteri for all your support and amazing contributions to this team. You will be missed. I wish you all the best for your future endeavours.
