Formula One's governing body on Wednesday rubber-stamped proposals for a mandatory two-stop strategy to help revive the Monaco Grand Prix as a spectacle.
The Mediterranean jewel in the F1 calendar on Monaco's distinctive twisty streets has remained largely unchanged since the first race staged there in 1929.
The top 10 last year finished in the same order they started, with the size and weight of modern-day F1 cars making overtaking all but impossible on the iconic 2.1 mile (3.4 km) circuit.
Max Verstappen finished sixth behind Charles Leclerc, complaining on his team radio during the race: "This is really boring. I should've brought my pillow."
Wednesday's decision, which will apply to both wet and dry races, has been pushed through "with the primary intent of improving the sporting spectacle" of the event, the FIA's world motor sport council announced at pre-season testing in Bahrain.
Drivers will now be required to use at least three sets of tyres in the race, with a minimum of two different tyre compounds to be used if conditions are dry.
