Fighting it out in the closing stages of the race, the Red Bull driver clipped the McLaren, forcing Norris to run wide over the kerb and the run-off area.
“Yeah, he just crashed into me,” Norris complained over the radio. “That’s just dangerous driving. He had loads of space.”
Perez, meanwhile, was indignant on the radio, asking: “Why are we given a penalty? I was ahead."
Perez's penalty ended up deciding the fight between Mercedes and Ferrari, as he passed George Russell on the track – which would have handed second in the championship to Ferrari.
However, not even some chicanery from Charles Leclerc could help Perez gain the five-second gap he needed to beat Russell after the penalty was applied, leaving Mercedes to take home about an extra $10m by the barest of margins.
