Last year in a similar situation at Interlagos, a civil war broke out in the Red Bull camp after Verstappen refused to let Perez by to score extra points.
It later emerged that it was seen by Verstappen as payback after Perez’s qualifying crash in Monaco several months earlier had stopped the Dutchman’s shot at pole.
Perez is currently lying second 20 points ahead of Lewis Hamilton with three events to go, including the sprint weekend in Brazil.

A one-two in the world championship is a prized target of team boss Christian Horner, as Red Bull has not previously achieved it.
Perez believes that this time around Verstappen will help if there’s a scenario where swapping the cars around will give the Mexican priceless extra points.
"We haven't thought about it,” said Perez when asked if he expected to have help from his team-mate. “But I think if the situation arises, I'm sure I would have support from Max."
When asked if he would support Perez this time, Verstappen opted not to give a clear-cut answer and instead hoped such a scenario won’t arise again this year.
