McLaren team principal Andrea Stella says the United States Grand Prix stewards have "interfered in an inappropriate manner" with Lando Norris' and Max Verstappen's battle for third, as Norris took a five-second penalty for passing off-track.
Norris had caught Verstappen in their hard-tyre stint and began to exert heavy pressure on his championship rival, although each of his efforts to pass was batted away by the Dutchman's well-curated defence.
