FC Metz secured the Domino's Ligue 2 title on Friday and will be back in the top flight next season after a one-year absence.
The Lorraine outfit clinched promotion last weekend with three matches to spare, and they followed that up by securing the league title on Friday with a 3-0 win at home to Valenciennes FC that featured two goals by Habib Diallo. It was their 23rd win in 36 matches this season.
Senegalese forward Diallo is the joint top scorer in the division with 25 goals this season and has been the driving force in securing Metz's return to the elite after just a year away.
Their title triumph has been achieved despite coach Frédéric Antonetti taking leave of absence back in December to care for his sick wife. Without him, assistant Vincent Hognon has overseen the side's run to the title.
Behind Metz, Stade Brestois 29 sit second but missed the chance to secure promotion back to the top flight when they lost 1-0 at struggling AS Béziers on Friday. The Brittany side, who last played in Ligue 1 in 2012-13, are four points clear of third-placed ESTAC Troyes with two matches remaining.
