Oscar Piastri wary of explosive McLaren history in Lando Norris title fight

Oscar Piastri is wary of "teams unravelling" in the white-hot environment of an intra-F1 title fight as he prepares to battle Lando Norris for the drivers' crown.  Piastri heads into the second-half of the season leading Norris in the sister McLaren by just nine points in the race to become the first McLaren drivers' champion since Lewis Hamilton in 2008.  Whilst relations between Piastri and Norris have been cordial up until this point, including a collision in Canada, CEO Zak Brown believes another collision is imminent owing to the close proximity of the two on track, having gone wheel-to-wheel for wins thrice in the last four races. In 1989, the relationship between McLaren team-mates Ayrton Senna and Alain Prost disintegrated as they fought for the crown in bitter circumstances, but Piastri believes a similar fate will not affect him and Norris. "We've always worked well together from the moment I joined the team, and we still work in the same way," Piastri told Sky Sports F1.  "Both of us like to think that part of the success is, in some ways, us working together and wanting very similar things from the car, but also just trying to set the example for the rest of the team.  "We've seen so many times in the past how not just drivers, but whole teams can unravel from friction and internal tension, but we get on well.  "We work together very well, and we also want this opportunity for as long as we're in F1, we don't just want it once this year, and that is important for us."
