The Giallorossi have cut into Inter Milan's lead with a superb run of form.
But Ranieri insists: "No, the title race isn't open again because we are doing a super job. We are still on the last big bend then we'll see the final straight.
"Inter are a great team. They are compact and decisive. On Saturday they deserved to win playing with nine men against 11.
"Our mind has now turned to the Europa League. We have to go through, both us and the other Italian teams in Europe, also to resolve the co-efficient."
