The Frenchman said that he is delighted with the forward's "positive attitude", hailing the way he has put his recent transfer saga behind him to focus on playing for the Foxes.
"We know the quality of Riyad and he is a valuable player for us. It is important he stayed, we know the stories from the transfer window but he returned to the squad with a good mentality, positive attitude in training and games," BBC Sport quotes Puel as saying.
"I am happy for him, he wanted to give his best for the team until the end of the season and it is a good reward for him. In the end he made the difference.
"It was the last opportunity to score in the game and quality players can make the difference from these situations. Him, Jamie Vardy or any other quality players. It is a crucial point for us because we gave our best in this game."
The result leaves the Foxes in eighth place in the Premier League table, while Bournemouth are four points behind in 11th.
