The victory eases pressure on OM coach Franck Passi, who Ayew is close to.
"I am very happy with the victory and above all for the team, for the fans and for Franck (Passi). I've known him since I was young. I hope the group will continue to look up.
"If they continue like this, the fans will follow and the stadium will be full. We had to bounce back, and they did it with force and strength, even if the last few minutes were more complicated.
"I'm also happy for my friend Bafé (Gomis)," said Ayew.
