Formula One ace driver Lewis Hamilton has said that Monaco Grand Prix could be a disaster as back markers will cause a smash on Monte Carlo's steel-lined streets.
Hamilton blasted the also-rans as dangerous in Spain on Sunday and says cars going six seconds a lap slower could cause a massive shunt.
"It could be a disaster. It's just very difficult when there is such a big difference in speed," The Sun quoted Hamilton, as saying.
"So far, fortunately, there have been no incidents and it's been okay. But Monaco will be very tough," he added.
Hamilton and team-mate Jenson Button know how dangerous Monaco's streets can be.
Hamilton smacked into the barriers in qualifying last year while Button was taken to hospital after a horrific 180mph shunt in 2003.
