Faltering in his title quest, Martin Brundle believes there are five reasons why Oscar Piastri is having a difficult time of late, and number five is Lando Norris.

With three race weekends remaining this season, Piastri finds himself trailing Norris by 24 points as his streak of races without a podium finish extended to five at the Brazilian Grand Prix.

Oscar Piastri’s troubles: Does Martin Brundle have the answers?

⦁ Piastri troubles down to head, luck, setup, tracks, and Norris
⦁ McLaren driver pinpoints a sixth reason, Monza team orders
⦁ Another momentum swing is not inconceivable

Winning the Dutch Grand Prix when Formula 1 returned from its annual summer break, Piastri surged 34 points ahead of his teammate Norris.

It was his seventh win of the championship and his 13th podium in 15 races before the Aussie added a 14th at the Italian Grand Prix. That, though, was his last top-three result.

Blighted by a barrage of crashes in Azerbaijan and the Austin and Brazilian Sprints, he was then penalised for causing a collision in the Brazil GP where he finished down in fifth place.

With Norris claiming the win after starting on pole in arguably the Briton’s most dominant race weekend of the season, as he also won the Sprint from lights to flag, Piastri trails his teammate by 24 points with 83 still in play.

It’s been a huge turnaround in form with Piastri once the standout driver, but now it’s Norris.

It begs the question, where has it gone wrong for Piastri?

Former F1 driver turned Sky Sports pundit Brundle believes he has the answer.

“Piastri was so unlucky again, the dice simply won’t roll for him,” he wrote in his column for Sky F1.

“The last time he was on the podium was back in September in Monza. He’d been on the podium 13 of the 15 races prior to that including seven victories.

“Norris was quicker than him in Monza, followed by the double shunt and jump start horror story in Azerbaijan, the first-lap skirmish with Norris in Singapore, the Sprint race in Austin which cost both cars heavily, and his pace simply hasn’t quite been there since.
