The young Canadian will join Williams next year after winning the European Formula Three championship.
But despite question marks over the 18-year-old's talent and comments labelling him as a 'pay driver', Bottas expects Stroll to perform straight away next season.
"I don't need to advise him, he's a talented driver," Bottas told ESPN. "I'm sure he'll learn a lot quickly and he'll be up to speed very quickly. As a team, we'll do everything we can to help him improve.
"There are plenty of things to learn when you jump from any category. There are many more people in the team, there is a lot you to learn technically from the car so I will help in the ways I can. He has plenty of talent, I am sure he will do fine.
"He's going to learn quickly, I'm looking forward to being paired with him and pushing the team forward."
