Mason Greenwood's late penalty propelled Marseille past Monaco with a 2-1 victory in Sunday's eye-catching Ligue 1 clash.
Greenwood converted from 12 yards with just a minute of normal time remaining, moving Marseille up to second in the table and ahead of Monaco on goal difference.
The spot-kick was awarded for a handball from full-back Christian Mawissa as Marseille ended a three-game winless run against Monaco in the league.
Valentin Rongier's poor pass in the first half had earlier allowed Aleksandr Golovin to counter-attack and open the scoring with just his second Ligue 1 goal of the campaign.
Luis Henrique subsequently levelled before the hour, capitalising on some fine work from Neal Maupay, before Greenwood snatched victory for Roberto De Zerbi's side.
At the other end of the table, bottom side Montpellier salvaged a 2-2 draw with fourth-placed Lille thanks to Arnaud Nordin's last-gasp leveller in an ill-tempered clash.
Jonathan David had earlier scored a penalty in either half for the visitors, with Issiaga Sylla on target for Montpellier on the stroke of half-time to level after the Lille forward's first spot-kick.
Montpellier head coach Jean-Louis Gasset was sent off late on before Tanguy Coulibaly and Mitchel Bakker were both dismissed in a chaotic ending.
Coulibaly prompted the altercation by kicking the ball against Lille head coach Bruno Genesio, with Bakker and the Montpellier man taking the punishment for the clash that subsequently followed.
Far less drama ensued in Lyon's routine 4-1 victory over Nice as Alexandre Lacazette's hat-trick helped his side move into fifth place.
Sofiane Diop managed an equaliser for sixth-placed Nice after Lacazette's opener, only for the Lyon striker to put the visitors to the sword along with a goal from midfielder Jordan Veretout.
Sunday marked the seventh time Lacazette has scored three or more goals in a Ligue 1 game, more than any other Lyon player in the competition's history.
He also scored his 149th, 150th and 151st Ligue 1 goals. In the 21st century, only Kylian Mbappe (191) and Wissam Ben Yedder (161) have scored more in the top-flight.
