Kimi Raikkonen has upped the ante in his war of words with McLaren's Sergio Perez by suggesting that someone should "hit him in the face".

Perez blamed Raikkonen for the accident in Sunday's Monaco Grand Prix which ended his hopes of his best finish since joining McLaren. Lotus driver Raikkonen, however, described Perez as an "idiot", and that was prior to the 69th-lap shunt that saw the Finn suffer a puncture and Perez lose bits of his front wing.

The Mexican has raised eyebrows in Formula One with his risk-taking style ever since he came into the sport in 2011 and, when asked by journalists whether the drivers should get together and speak to the 23-year-old, Raikkonen said: "I don't know. It is maybe better to hit him in the face and then he'll understand."

Perez had already pulled off daring late-braking moves on team-mate Jenson Button and Ferrari's Fernando Alonso into the chicane on Sunday afternoon.

On the first occasion Perez tried a repeat manoeuvre on Raikkonen it ended with both swerving to avoid one another and cutting across the chicane, in turn resulting in the 33-year-old's remark over the radio.

Second time around, however, Raikkonen squeezed Perez into a barrier, incurring a left-rear puncture and dropping him to 10th come the flag.

Although Perez managed to continue, he retired a few laps from home with overheating brakes at a time when he was running in fifth.

Far from believing he was over-aggressive, Perez said: "It was risky, but there was nothing I could do to avoid the crash. I overtook Fernando and Jenson in the same place, so at the end of the day you have to give some space.

"If you look at the accident I hit the wall on entry of the corner, so Kimi gave me no room at all and there was nothing I could do to avoid it.

"If someone could have avoided the accident then it was Kimi and not myself."
