Ousmane Dembele scored again as Paris St-Germain beat Marseille to edge closer to wrapping up a 13th Ligue 1 title.

Following his crucial midweek goal at Liverpool in the Champions League, in-form Dembele set hosts PSG on their way in Le Classique with a composed 17th-minute finish after Fabian Ruiz's pass.

The France international has scored seven goals in his latest seven appearances, with his latest effort taking his season's tally to 30 in all competitions.

Ruiz grabbed his second assist of the night shortly before half-time when midfielder Nuno Mendes stroked in from close range.

Amine Gouiri scored his fourth goal since joining Marseille in January to offer hope of a comeback early in the second half; however, a Pol Lirola own goal put PSG back in control.

The Paris giants have yet to lose in the league this season, winning 21 games and drawing five, and they have won 11 of 13 played at the Parc des Princes.

Victory extends PSG's lead over second-placed Marseille to 19 points and means they could wrap up the title with six games to spare on 5 April if they win their next two fixtures against Saint-Etienne and Angers.

PSG have won the Ligue 1 title in each of the past three seasons and remain on track for a treble with a place in the Coupe de France semi-finals secured, while they face Aston Villa in the quarter-finals of the Champions League.
