"I want to focus on the win, because that is what we needed," said Fournier after the game.
"We'd been chasing after one for a while. It was a hard-fought victory, because Monaco put all their attacking talents on show in an attempt to equalise. It's not an undeserved win either, though.
"We showed great fragility at the back, notably in the first half. We, unsurprisingly, found ourselves pegged back after a couple of scares that we didn't pay heed to."
The result leaves Lyon sitting in 13th spot in the Ligue 1 table.
