The incident that is bound to create problems at McLaren came as Norris dived down the inside of Piastri after making a good start from fifth on the grid.

Norris was caught out by Verstappen slowing more than he expected in the middle of Turn Three.

Norris touched the Red Bull, damaging the McLaren’s front wing endplate, and that bounced him side-on into Piastri, whose momentum was checked, allowing Norris to move ahead into third place.

McLaren’s internal rules dictate that the drivers are free to race but must not make contact with each other.

Piastri said over the radio: “That wasn’t very team-like, but sure.”

Shortly afterwards, he added: “Are we cool with Lando just barging me out of the way?”

His engineer Tom Stallard said the team were “looking at it”, before coming back to tell Piastri that they would take “no action in the race” because “Lando had to avoid Verstappen” and that they would “review it afterwards”.

Piastri replied that the decision was “not fair” and used an expletive in relation to Norris avoiding Verstappen “by crashing into his team-mate”.

Norris said: “It was slippery, but it’s racing. I put it on the inside, had a small correction but nothing more than that. It was good racing. I felt like I did everything I could today but I’m happy with that.”

The context for the incident is a series of situations in which McLaren’s manner of operating their internal policy has gone against Piastri.

In Hungary in August, Piastri was the lead McLaren driver but Norris was allowed to switch strategies in a move that eventually led to him winning the race.

In Italy in September, McLaren ordered Piastri to give second place back to Norris after a slow pit stop for the Briton, in combination with an unusual team decision to pit Piastri, the second of the two drivers, first led to Norris losing second place.

Piastri objected to that decision, saying he thought they had agreed that slow pit stops were to be considered part of racing, and therefore not something that should be corrected. But he acquiesced.

Internal discussions followed that incident, as they surely will this one.

The row took some of the shine off McLaren’s constructors’ triumph, their second in a row, and won with six races still remaining – the same point of the season as Red Bull sealed the title two years ago.

It is a reflection of a season of consistent excellence. The car was on average the class of the field, if less dominant than Red Bull’s in 2023, and they had both drivers delivering results at the front.
