Lille edged closer to their first Ligue 1 title in 10 years as a Burak Yilmaz double inspired them to a 3-0 win at 10-man Lens.
Yilmaz scored an early penalty before Clement Michelin was sent off for two yellow cards within 35 minutes.
The visitors capitalised with Yilmaz’s 25-yard stunner, before Jonathan David added another after the break.
With two games left Lille are four points ahead of Paris St-Germain, who have a game in hand at Rennes.
Lille, last crowned champions in 2011, are looking to become the second club – after Monaco in 2016-17 – other than PSG to clinch the Ligue 1 title since 2013.
