Toto Wolff has disagreed with McLaren's view that Red Bull stretched the boundaries of sporting integrity in Singapore.

Marketed as a farewell gift to Daniel Ricciardo, Red Bull Racing's sister team RB had the Australian make a late pit stop, allowing him to chase the fastest lap of the race.

Despite not earning the bonus point, as Ricciardo was outside the top 10, the move did prevent Max Verstappen's title challenger Lando Norris from securing the extra point.

"It's disappointing from a sporting point of view," remarked McLaren CEO Zak Brown, accusing the two Red Bull-owned teams of collaborating unfairly on the track.

"There shouldn't be A and B teams or sporting collusion on the track," Brown added. "And that's exactly what it was. Hopefully this point won't make the difference in the end."

However, when asked about Brown's and McLaren team boss Andrea Stella's claims of unethical behaviour, Mercedes boss Toto Wolff didn't share the same opinion.

"I think you probably have to use all the strategies you have," Wolff, often aligned with Mercedes-powered McLaren and a regular critic of Red Bull, commented.

"I don't think it was an unsportsmanlike action. Not at all," he continued.

"Championships can come down to one point, and what they (Red Bull) did was within the rules, the drivers were not unfair to each other on the track – Ricciardo simply did the fastest lap."

"No problem," Wolff concluded.
