Yuki Tsunoda has revealed the damage Sergio Perez did to his AlphaTauri in their first lap collision at the Singapore Grand Prix.
Starting 15th and 13th, respectively, Perez tried a move up the inside of Tsunoda at Turn 5, but misjudged and clattered into the right-hand side of the AT04.
Tsunoda managed to struggle on until pulling off at Turn 14 and to retire, meaning he has not completed a racing lap in the past two races after the car failed on the formation lap at the Italian Grand Prix.
But the Japanese racer was left frustrated knowing that there was pace in the car, with team-mate Liam Lawson finishing ninth.

Tsunoda reflects on DNF
"I had a good start and it is a shame how it ended up, it's frustrating," Tsunoda explained to media.
"The sidepods are completely gone after the contact.
"There was a loss of aero and loss of grip on the [right] hand-side [meant I had to retire].
"At least the car pace was good [throughout practice]. I feel bad and sorry for the team because I couldn't extract performance, but I'll just have to bounce back strongly in Suzuka."
