For this third preparation match, OGC Nice faced Celtic, the Scottish champion, at the Groupama Stadium in Lyon as part of the Veolia Trophy.
Kasper Dolberg opened the scoring in the 39th minute for the Gym after a solo raid in the Scottish defense.
In the second half, the incoming Nice goalkeeper Boulhendi missed his clearance and saw his ball intercepted by Klimala, who only had to push the ball into the back of the net.
The two teams parted with the match ending in a draw.
The Nice team is slowly gaining momentum just over a month before the start of the new Ligue 1 season.
