PARIS — Olivier Giroud's mistake gifted Emmanuel Emegha his second goal as Strasbourg won 2-0 at home to Lille to move provisionally up to fourth place in Ligue 1 on Sunday.
Lyon has a chance to move into fourth spot with a home win against injury-hit Paris Saint-Germain later Sunday.
Giroud is France's all-time leading scorer with 57 goals and won the World Cup, the Champions League with Chelsea and Serie A with AC Milan in a highly successful career.
But despite his vast experience, he made a poor mistake as he passed the ball back from midfield without looking up and failed to spot Emegha nearby.
The Dutch forward ran through the middle, shook off two defenders, and finished confidently in the 62nd minute. He had opened the scoring in the 33rd when he turned in Diego Moreira's cross with his knee.
Elsewhere, Metz's mini-revival continued with a 2-1 home win against Nice to make it three straight victories after failing to win the first nine.
Winger Mohamed-Ali Cho gave Nice the lead in the 35th with a left-footed finish. Captain Gauthier Hein equalized with a penalty early in the second half to continue his recent scoring form and striker Habib Diallo netted a late winner.
PSG injuries
Coach Luis Enrique's PSG side went to Lyon without Ballon d'Or winner Ousmane Dembélé (calf tear), right back Achraf Hakimi (sprained ankle), left back Nuno Mendes (sprained knee) and rising star Désiré Doué (thigh tear).
Nine PSG players have been injured since August, while Dembélé and Doué have been injured twice.
Other matches
Also Sunday, struggling Lorient drew 1-1 with Toulouse and Angers won 2-0 at home to rock-bottom Auxerre.
Lorient striker Pablo Pagis — whose father Mickaël was also a forward — scored with a penalty close to halftime. Veteran Djibril Sidibé equalized from the spot.
Angers took a second-half lead with an own-goal from Norwegian defender Fredrik Oppegard and substitute striker Peter Prosper made the win safe late on.
