City are in pole position for a return to the Championship but as the midweek draw with Brighton showed you can't get three points every week. City must remain confident but not complacent.
Leicester City assistant boss Craig Shakespeare told BBC Radio Leicester:
"We're going into the game very positive - we know we're playing well and have players who can win games.
"We know it's going to be a difficult game but there won't be any easy games from now until the end of the season."
Northampton won their last home game 5 - 1 with new signing Billy Sharp scoring a hat trick on his debut.
