"If you are racing for the championship and you see it fading away because the other guy is overtaking you, what tool have you got other than the one that makes sure he can't overtake? We've seen it with Schumacher and Villeneuve, we saw it with Senna and Prost twice.
"I would never give the instruction to crash into anyone else but if they go to that last race and whoever is in front wins the championship, they will be racing each other, hard.
"And I don't think you can control it, Hamilton and Verstappen, I don't think you want to control it because they are the gladiators in their machines.
"That is what makes this sport so interesting, because it is ingrained in our nature that we don't like confrontation and then one is intrigued to see how that relationship unfolds.
"If they crash are they going to confront each other? What are they going to say? Will they look in each others' eyes?
"We would not interfere. The relationship is sorted out between the individuals."
