The Ivory Coast international struck a last-minute penalty, having already equalised, as the Swans beat Newcastle United 2-1 at St James' Park this afternoon.
He told Sky Sports: "It was a great performance and we are happy with that. But we deserved to win. They scored by a mistake and we just deserved it.
"If we can win our last three games, then we should be OK. It's very important to win. The fans are confident in me and it's important to keep them happy and me."
