Oscar Piastri labelled McLaren's decision not to make Lando Norris give him back position after a racing incident between the team-mates at the Singapore Grand Prix as "not fair".

McLaren secured the Constructors' Championship in Formula One with six races to spare, but the celebrations were soured by an incident at the first corner between the pair.

Norris managed to pass Piastri, who is leading the drivers standings, but made contact with the Australian as he tried to avoid defending champion Max Verstappen.

Piastri said over the team radio, "that wasn't very team-like, but sure," before adding, "Are we cool with Lando just barging me out of the way?"

When told the team would take no action because Norris was attempting to take evasive action with Verstappen, Piastri said it was "not fair".

Piastri finished fourth in Singapore, with Norris coming home third behind race winner George Russell and Verstappen.

Norris is now only 22 points back of Piastri, the latter of whom cut a more diplomatic tone when speaking to Sky Sports.

"Yes I think we do (race clean). I don't think there was any intention of contact but there was and I need to look at the replay and look at exactly what happened."

Asked if the team needs to review its own internal rules, he added: "I don't know, I've not seen the incident. I need to look at that first before I say any comments."

McLaren team principal Zak Brown put the incident merely down to "hard racing".

"Like all race weekends, you review everything. First corner, looks like Max and Lando either touched or had to check up," he said.

"But it was an exciting Turn Two incident, so racing, tough racing, you got three or four cars stacked up, so that's going to happen every once in a while. 

"So, we will look at it in more depth on Monday, but clearly just hard racing."
