Sergio Perez: Singapore Sirotkin clash looked 'worse from outside'

Having edged ahead of Sirotkin, Perez darted to the inside line on approach to the Turn 18 left-hander and clattered into his rival's Williams.

The collision earned the Mexican a drive-through penalty and three penalty points, a sanction Perez described as "fair" in the immediate aftermath of the race.

Asked by Autosport whether he's reviewed the incident since, Perez said: "Yeah, I've obviously seen it, and in my opinion it looks a lot worse from the outside.

"Basically, with these mirrors it's very hard to see behind, so I lost the reference, I thought I already did the move in the first corner [the preceding Turn 17 right-hander].

"I actually was speaking on the radio at that point but then I saw him, and then I just misjudged where he was.

"I was trying to close the door before braking but he was just too close to it. It was just my fault, got a penalty, which I think was right.

"Nothing to say, really, other than accepting my mistake."

Perez was admonished for the crash, and the fact he was audibly frustrated behind Sirotkin before the incident led to suggestions his move was deliberate.

But FIA race director Charlie Whiting described the claim as "hard to believe", and when himself asked about the theories, Perez said: "Yeah, I think they're too harsh. Probably the way it looked from the outside.

"I ruined my race, I wouldn't have done it on purpose."

Perez had repeatedly called for Whiting to look into Sirotkin's defending in the lead-up to the accident, and has stood by the criticism despite noting that the Russian "did a good race".

"I was complaining to Charlie because he was moving quite a lot on braking, which is not ideal, you know, you can cause collisions when you're moving under braking.

"But that has nothing to do with the incident, the incident was not his fault, was my fault."

Sirotkin said he has viewed "all the replays of every lap" and seen nothing that could have triggered his rivals complaints.

"There wasn't a single time where I moved under braking," he said. "It shouldn't be mixed up with - in Singapore, when you approach braking zones, you don't always approach in a straight line, and it's simply a question of at which point you put your car at the angle to brake straight.

"I was honest in my position after the race, claiming that I did nothing wrong. And this is my conclusion still."

Sirotkin refused to say whether Perez's drive-through was a sufficient penalty, but added: "Really everybody's only noticing the one incident, but they shouldn't forget that we were fighting for many many laps, many corners before on that same lap.

"So there's no need to exaggerate anything - it was a tight, hard fight, but very fair and very precise."
