The former Silver Arrows star got the better of the Brit in 2016, during a season that saw the pair’s relationship become strained as both battled each other for glory.
Speaking with France’s Auto Hebdo, Rosberg believes that the only possible way the Finn can claim success for himself is to “destabilise” the six-time winner.
Rosberg said: “I remember realising that his [Hamilton’s] defences had been broken when he started playing with Snapchat during a press conference.
“The next day, he performed poorly. It all plays a role. It may seem insignificant, but these things can unsettle you. It must be understood that the more you attack him and the more aggressive you get with him, the stronger he becomes.
“Valtteri needs to always be there as a strong opponent performing with stability. He needs to become obsessive, so that Lewis feels his presence.”
