RACE DEBRIEF

    Fans were back in the grandstands lining the sun-soaked Monte Carlo streets to witness Sergio Perez set the fastest lap in first practice for Sunday's Monaco Grand Prix, ahead of Ferrari's Carlos Sainz and Max Verstappen – the top three split by just 0.161s.

    Red Bull, hunting for their first victory in Monaco since 2018 – and first win since Imola – had soft tyre-shod Perez set the benchmark late in the session, improving to 1m12.487s with his final run. Medium-tyred Sainz was second by just 0.119s in an impressive showing for Ferrari, followed by Verstappen on the same compound, another four-hundredths of a second off.

    Pierre Gasly put his soft-tyred AlphaTauri fourth, four-tenths off the pace. That left the medium-tyred Mercedes of Lewis Hamilton and Valtteri Bottas in fifth and sixth respectively.

    Charles Leclerc, sporting a helmet in tribute to Monaco legend Louis Chiron, began the session waving to his home fans, but the Ferrari driver's gearbox gave way soon after and his session was over after just four laps. He finished bottom of the time sheets as a result.

    Aston Martin's Sebastian Vettel won here in 2011 and '17, but is still getting to grips with things at his new team. He finished eighth, behind Norris, while team mate Lance Stroll was 11th. Between them was AlphaTauri's Yuki Tsunoda (P9) - who is competing at Monaco for the first time in his racing career - and 10th-place Kimi Raikkonen for Alfa Romeo.

    Antonio Giovinazzi was next, in 12th, and behind the Alfa Romeo in the standings was 13th-place Fernando Alonso of Alpine. Winner here in 2006 and '07, Alonso tapped the wall on Thursday morning in the final corner and brought out a Virtual Safety Car just before the half-way point of the session. Team mate Esteban Ocon, ecstatic about returning to Monaco after a three-year absence, took 16th overall.
