Max Verstappen left it until the final seconds to take a sensational pole position at the Monaco Grand Prix.
In the most important qualifying sessions of the year, thanks to the nature of the circuit making it difficult to overtake, the double world champion finally found a way to overcome a rapid Fernando Alonso.
A time of 1:11:365 was more than good enough to claim pole position, giving him a very good chance of victory and a substantial championship lead.
Alongside him on the narrowest grid of the season will be Alonso, who looked likely to take pole before a stunning final sector from Verstappen.
Charles Leclerc will start third for Ferrari, although he is under investigation for impeding Lando Norris in Q3, alongside Esteban Ocon who was on provisional pole with a couple of minutes to go.
Perez throws it away
With just seven minutes on the clock, Sergio Perez crashed out of qualifying at Sainte Devote, damaging his Red Bull car and bringing out the red flag.
A rear-end slide saw his RB19 slam into the tyre wall and end his qualifying day there and then, even though he was fifth fastest at the time of the crash.
It means starting way down in the field at the most difficult-to-overtake track in the world, leaving the chances of even points slim at best.

The lap times were extremely close throughout the day and Lance Stroll was a major casualty of Q2.
Stroll could not match Alonso's speed in the Aston Martin and qualified 14th on the streets of the principality.
His lack of speed certainly helped Lando Norris who damaged his suspension towards the end of Q2 and couldn't get his final lap in. The Brit did sneak through in 10th.
Cutting it fine
It was a very frantic Q1 session after Perez's Red Bull was cleared away with Lewis Hamilton and Carlos Sainz both cutting it fine.
The Mercedes and Ferrari duo had to put it all on the line on their final laps to make it into Q2 along with their teammates.
Yuki Tsunoda and Alex Albon were the stars of Q1, ending the 18 minutes second and third respectively.
After all of that, it was a fairly standard drop zone, Perez excluded, with Zhou Guanyu 19th behind the two Haas' and Logan Sargeant.
