I don't know why I would blame Vettel for a terribly timed and executed move from Verstappen
Vettel is one of the worst crybabies in F1 history, there's no doubt about it, but in this case he would be right to complain. If Verstappen had simply waited one or two turns, he would easily have passed Vettel, the Ferrari was almost going backwards as a matter of speech. Luckily Verstappen reacted as usual: realistic. In this case by very simply starting the interview with "I screwed it up myself". Well, yeah, not much more to add to that.
