Frustrated Magnussen was hoping "engine would blow up"

Magnussen started fifth and best of the rest in Monaco, but lost a place to Daniel Ricciardo at the start.

However, along with Ricciardo and others, he then fell down the order when he pitted under the early safety car, while rivals stayed out.

He eventually crossed the line in 12th, but lost two further places for gaining an advantage while battling with Sergio Perez.

Magnussen realised soon after the safety car that he was in trouble and resigned to a long slog to a finish outside the points.

"I wanted the engine to blow up," the Dane told Motorsport.com. "It's disappointing to have a result like today when we've been so strong all weekend and the team has done an amazing job.

"They provided me with exactly the tools I needed to perform. We've just been really good this weekend.

"I feel very sorry for everyone. I don't want to draw any conclusions over what happened – I just feel sorry for everyone, and I'm very disappointed for myself."

Magnussen said it's not easy for teams to always make the right calls in race conditions.

"It's very easy to draw conclusions. Things are happening very quickly, you have to take decisions in split seconds, and sometimes it goes well, and sometimes it goes wrong.

"You've got to give it to the guys, they're under a lot of pressure, and I don't want to blame anyone. It's a disappointing one, for sure."
