Pirelli motorsport chief Mario Isola is concerned a long safety car period during the Formula 1 Monaco Grand Prix could lead to issues in the pitlane, suggesting it will take a "genius" rather than a strategist to work out how best to attack the race, now that using at least three tyres sets is mandatory.
F1 will enter the unknown when the lights go out on Sunday afternoon, with the decision to make each car theoretically stop twice during the race coming into effect for the first time in an attempt to bring more entertainment to the grand prix around the tight and twisty streets of Monte Carlo.
