Ethan Mbappe, brother of France and Real Madrid superstar Kylian, scored deep into second-half added time as Lille fought from a goal down after regulation time to beat Toulouse 2-1 in Ligue 1 on Sunday.

A 90th-minute penalty converted by former Tottenham midfielder Nabil Bentaleb had brought the hosts level before 18-year-old Mbappe volleyed home eight minutes into injury time to seal the win.

Both goals came courtesy of late substitutes introduced by coach Bruno Genesio, with Toulouse down to 10 men after 80 minutes after midfielder Alexis Vossah's sending off.

Following his departure from Paris Saint-Germain in the wake of his elder brother's acrimonious free transfer to Madrid, Mbappe joined Lille in July last year.

The midfielder's first strike for the 2020-21 Ligue 1 winners came on his 11th league appearance as he ghosted in at the far post to thrash Osame Sahraoui's stood-up cross past the helpless visiting goalkeeper.

Frank Magri opened the scoring for Toulouse early in the second period before Lille's late show.

The last-gasp win took Lille to the top of the Ligue 1 table, with 10 points from four outings.
