In-form Leicester are likely to face a stern test from Chelsea on Monday night as they look to hold onto their lead at the top of the Premier League standings.
Claudio Ranieri's side have been the surprise package thus far, led by the scoring exploits of Jamie Vardy, who set a new top-flight record in the 1-1 draw against Manchester United by netting in 11 consecutive games.
That fine run came to an end last weekend when Vardy failed to score in a 3-0 win over Swansea, although he provided the assist for Riyad Mahrez to complete his hat-trick.
The Foxes are the form team in the league as they head into the clash at the King Power Stadium on the back of an eight-game unbeaten streak.
The 14th-placed Blues, meanwhile, suffered their eighth loss of the campaign when they went down 1-0 to Bournemouth last time out.
Jose Mourinho thought his team had begun to turn the corner following a 1-0 win over Norwich and a goalless draw against Tottenham, but they were stunned by the Cherries at Stamford Bridge.
In team news, Ranieri welcomes back on-loan Swans winger Nathan Dyer, who was ineligible to face his parent club.
The Italian remains without defender Ritchie de Laet (ankle) and midfielder Matty James (knee), who is close to making his comeback.
Mourinho has a fully-fit squad at his disposal and has some decisions to make, with John Terry, Ramires and Radamel Falcao all back in contention.
Centre-back Terry and midfielder Ramires both returned from injury in midweek to help the west Londoners qualify for the Champions League last 16 with a 2-0 win over FC Porto.
Striker Falcao has missed the last six outings with a muscular problem, but is fit again and could get a run-out in the East Midlands.
