Mahrez, who missed six training sessions and two games in a period of absence for the Foxes, insisted in a statement that he is fully committed to the club.
Manaher Puel has added to the comments following the Algerian's return to first-team action against Manchester City last weekend.
"Yes, I think better," the coach told reporters at a press conference when asked if Mahrez had turned a corner. "He enjoys playing and training with his teammates. He is at a good level and without problems.
"I think it is important now to put an end to the talking about Riyad. He has come back, he came in against Manchester City. Now we need to move on and for him, he has to kick on.
"The most important thing now is the future."
Mahrez could feature in Leicester's FA Cup clash with Sheffield United on Friday.
