Leicester manager Nigel Pearson is expected to name the same starting 11 that comfortably beat Ipswich in their previous clash.
The table toppers look like they are certain to be playing Premier League football next season but will face a stern test on Saturday after Charlton's last minute winner against QPR last weekend.
Pearson will not allow his side to under-estimate Chris Powell's side who beat the Foxes 2-1 back in August.
"Whatever has happened to their season so far, we know it will be a very tough game for us,
"I think it is one of those games where you under-estimate them at your peril. They will try to get their preparation right and they come into this game on the back of a couple of good wins.
"As always, we will have to be close to our best as we can to win this game." He told the Leicester Mercury.
In fact Leicester haven't beaten Charlton in the league since 2000, a run that stretches back 10 games. Even with history on their side it will still be very difficult for the Addicks as they travel to the most formidable home side in the league. As Pearson's men have only lost once all season, against Nottingham Forest.
However, the Charlton boss is going into the game in a positive fashion, despite their lowly league position:
“We go to Leicester who are a top, top side in the Championship and flying, but we go there on the back of a clean sheet in the league and a superb performance away from home in the cup.
“We have got two terrific results which have picked up everyone, and we go to Leicester in good heart, which helps." he explained to the clubs official website
Powell can included full back, Rhys Wiggins and goalkeeper, Ben Hamer in his starting line up if need as they return from injury.
Despite a recent good run for the Addicks, with a FA Cup quarter final showdown against Sheffield United coming up, that gives the club a real chance of a turnout at Wembley, the Foxes should dominant this game.
HITC prediction: Leicester City 2-0 Charlton
