The Blues put down a Premier League title marker with their 3-1 away victory over Burnley earlier this week.
They fell behind on 13 minutes but were imperious from thereon in, delivering a performance that justifies their status as pre-season championship favourites.
The 2013-14 Championship winners twice came from behind to gain a valuable point on their return to the top flight, against a side who are expected to be challenging for the top four.
Chris Wood's late equaliser against Everton may not be enough to earn him a starting berth, with Pearson likely to persist with David Nugent alongside record signing Leonardo Ulloa, who netted on his Premier League debut.
Reports have suggested that Cech will now seek to leave Stamford Bridge before the end of the transfer window, but Mourinho is keen to keep hold of the 32-year-old.
Some good news for Luis this week was his recall to the Brazil squad, and his international compatriot Ramires is back in contention for Chelsea after serving a suspension carried over from last term.
The Londoners have won their last six matches against Leicester and scored 20 goals in the process.
Possible starting lineups
Chelsea: Courtois; Ivanovic, Terry, Cahill, Azpilicueta; Matic, Fabregas; Schurrle, Oscar, Hazard; Costa
Leicester: Schmeichel; De Laet, Moore, Morgan, Konchesky; Mahrez, Hammond, King, Knockaert; Ulloa, Nugent
