Leicester are eighth in the Premier League and only eight points behind Arsenal, who are in sixth.
But boss Claude Puel says he is not allowing himself to be distracted by thoughts of Europa League qualification.
"If we begin to think about Europe, it will be the beginning of the end," he said. "It's important to keep a good focus and concentration on our play. I cannot have a view about Europe."
The Frenchman said he is not currently close to making any signings during the January widow.
"We are not close for the moment to sign a player," he added. "If we cannot find a player with good attributes who can give other strengths, it is important to keep this squad.
"If we can improve, we will sign. For the moment, it is not important."
