Mahrez struck six minutes into added time to earn the point.
Puel declared: “I think it is fantastic [that Riyad Mahrez scored at the end]. It is a good reward for Riyad and the team also. I said he will come back with a good attitude, a positive attitude. He has shown that in this game and in the last game also.
“It was a fantastic mentality with good focus and concentration. I am happy about this. It shows his good mentality and positive attitude. I am proud about him and his team-mates also. It is good for all the squad that he comes back with a good spirit in the team. He is a valuable player for us and he showed his quality and his good mentality also.
“That is important. When he came back into the team we got fantastic support from the fans. They can see he is here with us and he can make the difference, because he is a great player but also because he has a good mentality."
