Sergio Perez has labelled his first lap contact with Valtteri Bottas as a "massive shame" after it broke his front wing in the United States Grand Prix.
Perez had qualified the Red Bull in fourth, but dropped to ninth as he had taken new engine components, and was battling side-by-side with the Alfa Romeo of Bottas on the opening lap.
At Turn 9, Perez slithered up the inside of Bottas, but collided with the front-left of the Alfa, breaking part of the end-plate of the RB18.
While the piece eventually detached itself and Perez did not need to replace the wing at his pit-stops, the Mexican still felt the mishap had cost him in the race.

"It was pretty exciting to be battling with Charles [Leclerc] and with George [Russell]," Perez told media, including RacingNews365.com.
"It was a massive shame that we lost half of the front wing. I was inside [of Turn 9], but he didn't see me and just turned in.
"I think it hurt the balance quite a lot, but it is what it is. Once we managed to fix it, we were able to go quick.
"The problem was in the second stint, they didn't know at that time what was missing."
