Leicester have already proved they can score goals - the problem has been at the other end.
The Foxes, along with Manchester City, are the only side to have scored in every league game this season. They have the same amount (14) as East Midlands rivals Nottingham Forest, who are third, but have struggled to keep the ball out.
Only the bottom three, West Ham and Brentford have conceded more than Leicester's 18 this season.
They were also exposed when losing 5-2 to Manchester United in the Carabao Cup last week and they return to Old Trafford on Sunday seeking defensive stability and improvement.
