Sergio Perez walks away from horror crash on opening lap of Monaco Grand Prix

Sergio Perez walked away unharmed from a staggering crash on the opening lap of the Monaco Grand Prix.

The 78-lap race was immediately red flagged after Perez’s Red Bull hit the barrier as the field made their way up the hill from Sainte Devote.

The Red Bull was destroyed on impact with all but one of the Mexican’s four wheels ripping off his car.

Perez, who started 16th, walked way from the high-speed crash with debris scattered across the street track.

The Mexican driver was sent into the wall after Kevin Magnussen’s front-left wheel made contract with the rear-right of Perez’s Red Bull.

Magnussen’s Haas team-mate was also taken out in the collision. “That was unnecessary,” said the German driver.

The incident was noted by the stewards but was cleared with no further action taken. Red Bull confirmed Perez was not required to go to the medical centre.

Magnussen, who is already on 10 penalty points and would have faced a ban if punished further, believed he should have been afforded more space by Perez.

“I just got pushed into the wall and made contact with him,” the Dane told Sky Sports F1.

“I trusted he was going to leave a space for me since I was there.

“You have to have a car width otherwise you leave the guy no option. It is unfortunate, a lot of cost for the team, a lot of work for the guys and a missed opportunity today.

“I don’t know. It is something they will look at. It is a big crash. From my point of view I was there and I got squeezed to the wall. I don’t know how they are going to look at it.”
