Stoke have taken 25 points from 27 games - their worst points return at this stage of a Premier League season and sit second bottom ahead of their visit to the King Power Stadium.
Paul Lambert has been in charge of four Premier League games for Stoke, winning five points. Stoke had won only four points from their previous eight games prior to that.
But Leicester manager Claude Puel is taking nothing for granted despite Stokes recent woes, saying: "It will be a tough game against this team because for me, we will not be playing against a 19th-placed team. They play well with good football on the floor, quality, good pressing, fighting spirit.
"At this moment, this is not a team playing for relegation. We need to be careful about this team because it has good potential. With (Xherdan) Shaqiri and (Joe) Allen, they can make the difference at any moment."
