Former Williams driver Jacques Villeneuve has revealed that the Monaco Grand Prix is "hell to work".
The Canadian picked up the drivers' title in 1997 for Williams, before going on to retire from the sport in 2006.
The 44-year-old believes that Monaco and its party atmosphere makes the weekend difficult.
"The driving is amazing, it's the weekend that's a pain," Villeneuve told BBC Sport.
"You can't sleep at night because there's music everywhere until six in the morning.
"It's hell to work, so that's the part that's not likeable because it's not like the good old days where you went to a gala the night before and got drunk and raced anyway. So Monaco is hell."
Lewis Hamilton went fastest in this weekend's second practice.
