The midfielder was tipped for a move away from the King Power during the summer, with Roma, Barcelona, Arsenal and Tottenham reportedly interested, but he eventually stayed and has found form in recent weeks.
When asked about his future, he told 'Sky Sports': "Yes I am happy, I am happy, I'm here four years and I love this club. I am very happy.
"I don't want to think about [January]. We still have 12 games to go until January, so if I think about January now I'm not going to play football.
"I need to play and concentrate on football and the team and we will see."
Mahrez will be looking to continue his fine form when Leicester face Manchester City at home on Saturday afternoon.
