The Foxes are flying high in the midst of a six-match unbeaten run and a 100% start to 2021. The most recent of those wins, against fellow form side Southampton on Saturday, was another demonstration of their possible title-winning credentials and their continued improvement under boss Brendan Rodgers.
Indeed, they can go top of the Premier League table, albeit for perhaps only 24 hours, with all three points tonight.
By way of contrast the visiting Blues are struggling. Frank Lampard is fighting for his job after a series of disappointing performances and results although he will be buoyed by the victory over Fulham at the weekend.
Mason Mount grabbed the only goal of the game there as Chelsea's expensively assembled forward line again failed to hit the mark, but the three points were all that mattered as Lampard battles to keep them in touch in the race for the top four.
Lampard will be expecting a much tougher test at the King Power Stadium, however, where the hosts have now won three on the bounce. For all their recent travails, Chelsea could still move within two points of the Champions League places with a victory.

Leicester set up well against Chelsea and are surely likely to cause them problems at the back even with the Blues’ improvements in that area this season. The Foxes can be got at too though, with Chelsea's own attack surely hopeful of doing some damage themselves. Expect goals but the hosts to win by the odd one. Leicester 2-1 Chelsea
