2016 F1 world champion Nico Rosberg has called on Ferrari to take action following Lewis Hamilton and Charles Leclerc's latest clash at the Mexico City GP, echoing the former's calls for Mercedes-like rules of engagement.

During Lap 1 of the Mexico City GP, Leclerc went wide when attempting to take first place from pole-sitter Hamilton - who then lost second to Red Bull's Max Verstappen - but the Monegasque stayed ahead in the opening stages of the race. While Leclerc later received a five-second penalty for the incident, Hamilton was left feeling the move cost him the win, later calling on "serious talks" at Ferrari.

Rosberg, who fiercely battled Hamilton at Mercedes in the 2010s as the pair's once strong relationship turned toxic, pointed particularly at the Leclerc's role in recent flashpoints, referencing the Ferrari duo's Lap 1 scrap at Monza earlier on in the season.

Speaking on Sky F1, Rosberg said: “Interestingly, it’s always Charles’ fault, isn’t it? It’s never Lewis’s fault. In the last couple of times, in Monza it was Charles, here it was Charles. Really [team principal] Fred Vasseur, he needs to start to act.”

After the Monza clash, Hamilton suggested Ferrari should introduce rules of engagement, similar to those between himself and Rosberg during their tense years at Mercedes. Following the latest incident in Mexico, Hamilton said "nothing really has been done" to address how the Ferrari duo go racing.

Rosberg has backed Hamilton's calls, with German echoing Hamilton's suggestion that clashes will continue to occur between the Ferrari drivers if nothing is done.

“Once again, as Lewis said before the race, there was no discussion. Like clear racing guidelines between the two. It needs to happen, otherwise it’s going to keep going like this,” Rosberg said.

“It gets really bad when the drivers take it in their own hands and disregard whatever has been discussed and just take it in their own hands and sort it out on track and barge the other guy out the way. That can very quickly happen and it’s already kind of happening.

“On the first wheel-to-wheel that they had at Turns 2 and 3, Charles was bouncing over the kerb into Lewis, he was not holding the line. So already that was too much from Charles.”
