Verstappen was on the receiving end of complaints from Raikkonen after some tough defensive moves as they battled for fifth place at the Hungaroring last weekend.

Despite Ferrari also questioning what Verstappen was up to with race director Charlie Whiting, the stewards elected not to launch an investigation.

That decision has left Perez feeling that the matter needs to be brought up in Friday night's drivers' briefing, so that there is a better understanding of what is and is not allowed.

Reflecting on the Verstappen/Raikkonen battle, Perez said: “That was too much – too much moving under braking. It is something that we need to clarify.

“We sometimes see drivers over-defending their positions and it can be quite dangerous if you are moving under braking, just at the last moment.”

When asked if he was disappointed there was no stewards' investigation, he said: “It is a bit inconsistent sometimes as we know, but as well – in the past we had freedom a bit more in the rules to fight harder for the position.

"But I think moving under braking at the last moment was not correct.

“I think we should talk about it and clarify it.”

Yellow flags okay

While wanting talks over driver etiquette, Perez said that the other controversy over yellow flags was not such a big issue.

“I think Nico proved that what he did was appropriate, and I think every driver will have done the same in his position,” he said.

“It was down to the FIA to see it and if they were fine with it, I don't see an issue to go too much into it.

"With Nico, for example, it was different because he could see there were double yellow flags and he could lift, come back on power, not lose too much lap time and it was the entry of a relatively low speed corner.

“For Lewis the car was stuck there so he has to lift, so it is also a bit of common sense in that respect. If the FIA was fine with that, it is alright.”
