With Arsenal and Manchester United safe in the semi-final places - both Frank Lampard and Brendan Rodgers will be looking to secure their own places.
Leicester have not been beaten by Chelsea within regulation time since 2017 and they start this game having lost only one of their last six home games across all competitions - the team that got the better of them being Man City.
Chelsea have a 4 game winning run as they travel to the King Power. In three of those games Chelsea led at half time. As a traveling side, they have proven their worth by scoring twice in four of their last away trips. They are however a side that still trades goals, having conceded in their last seven away games.
Ross Barkley is the only Chelsea player to have scored in two FA Cup games this season, while Leicester's Harvey Barnes scored against Chelsea in the league and away to Wigan in their cup win.
In the last six meetings of the sides, five games have produced two goals or less while the score has been nil-nil at half time in four of those games.
Eleven of Chelsea's last Cup games have seen four or fewer cards awarded - and with Mike Dean as the man in the middle today, that statistic could see an increase.
Kick-off at the King Power is at 4 o clock.
