Perez reveals crucial factor that could halt Red Bull run

Sergio Perez has insisted that tyre degradation will play a key factor in the outcome of the Australian Grand Prix on Sunday.

Mexican Perez will start the race from third on the grid, directly behind teammate Max Verstappen who scored his third pole position of the season, though is under investigation for allegedly impeding Haas' Nico Hulkenberg.

Verstappen will share the second row with Carlos Sainz while the other Ferrari of Charles Leclerc ended qualifying in fifth.

Perez's effort in Melbourne marked his best result in a qualifying session since last year's Belgian Grand Prix.

“I think definitely there was a bit more in it,” Perez reflected.

“My first sector was not great, especially Turn 1. I think on my final attempt, I didn't hook in the whole combination, which straightaway is a tenth and a half.

“But I'm happy. I think given how we've been during the weekend, it's been a very nice progression.”

The tyre factor

Ferrari has showcased strong pace throughout the weekend but couldn't usurp Verstappen to pole position.

However, Perez is expecting a closer tussle during the race as he stated that keeping on top of the tyres during the race will be a key factor in the final outcome.

Pirelli has brought the softest tyre range to the event, spanning the C3, C4 and C5 compounds.

“We got a fight on our hands [for the race] with the Ferrari, so and to the rest of the field because I think the degradation is going to be very high,” he said.

“Track position is not that relevant at the moment.

“We've changed our strategy for tomorrow and let's see who can survive the most on the degradation side.”
