Abdoulie Sanyang scored twice in a crazy seven-minute spell as Greneble defeated Laval 3-2 in the French Ligue 2.
Bambalie gave the hosts a 3rd-minute lead before Gasper added a second three minutes later.
The Jeshwang-born forward smashed in a rebound from 25 yards for a commanding 3-0 lead in the 10th minute.
Laval pulled a goal back 16 minutes later and after Sanyang limped off in the 41st minute, the visitors scored again on the stroke of halftime.
GF38 held on for their second win in three to move to 8th on the 20-team table with 16 from 11 matches. Bamba has played and started 10 of GF38’s 11 matches this season and is their leading scorer with five goals, just two behind the league’s top scorer Nigerian Joshua Maja.
