Diallo added his brace after strike partner Ludovic Ajorque netted early on as Strasbourg left struggling Metz as one of only four teams still looking for a win.

Ajorque put the Alsace-based side ahead from the penalty spot in the fifth minute following a foul on midfielder Dimitri Lienard.

Diallo finished well with a low shot in the 25th, thanks to good work from defender Gerzino Nyamsi, and struck again in the 39th when he latched onto Ajorque's excellent lofted pass.

Friday's victory moved Strasbourg up to 10th place ahead of this weekend's games while Metz dropped to 19th.

On Saturday, defending champions Lille look for only their second win this season when they travel to play fifth-placed Lens, who are unbeaten under coach Franck Haise.

Also, 18th-placed Saint-Etienne face last-placed Bordeaux with both sides chasing a first win.
