Everton fans are waiting to see whether Roberto deems Romelu Lukaku and Kevin Mirallas fit enough to start in the East Midlands. New signing Christian Atsu is in the same boat, while Seamus Coleman is close to returning from a hamstring problem.
Arouna Kone and Bryan Oviedo remain sidelined as they rehabilitate from long term lay-offs.
Nigel Pearson will monitor both Jamie Vardy and Marc Albrighton's fitness ahead of the start of the Barclays Premier League season.
Anthony Knockaert will miss out, as well as defender Matt Upson who is set to undergo surgery.
Leicester notched up six wins and a draw during an unbeaten pre-season campaign as they prepared for their return to the Premier League.
Indeed, one of thoe wins saw the Foxes secure a narrow victory over the Blues in Bangkok, thanks to a goal from Gary Taylor-Fletcher - and preparations continued to go well with wins against Walsall, Preston North End and MK Dons.
An impressive brace from new signing Leonardo Ulloa gave the Foxes a 3-1 win over Rotherham United before ending pre-season with a 1-0 home win over German side, Werder Bremen.
For the Blues, it's been quite the opposite in terms of results, with Roberto Martinez's side losing three and drawing two.
Pre-season began with a 2-2 draw against Tranmere Rovers before that trip to Bangkok.
Everton then played three games in a week, starting with Leon Osman's testimonial against Porto, where Steven Naismith scored the opener before the Blues were pegged back by the Portuguese outfit.
The Toffees ended their preparations with two tough tests against Celta Vigo and SC Paderborn, both games resulting in 3-1 losses.
Leicester City 1-1 Everton, Saturday 20th March 2004
Everton were denied three points by a last-gasp equaliser from soon-to-be Blues striker, Marcus Bent.
Duncan Ferguson was sent off at the Walkers Stadium, which left the Blues down to ten men with the second half to play. That incident will be long remembered following the fiery Scot's infamous 'confrontation' with Steffen Freund.
With just 15 minutes to go, Wayne Rooney looked to have given Everton the win after netting the opening goal but deep into stoppage time, Bent climbed highest in the box and nodded home a late equaliser to deny Everton the three points.
One to Watch
Lifelong Evertonian, David Nugent scored 22 goals in all competitions last season to help the Foxes win the Championship title.
It proved to be Nugent's most successful campaign in his career to date, as he formed arguably the most lethal partnership alongside Jamie Vardy, scoring a total of 38 goals between them.
Nugent has previously scored just nine goals in three seasons in the Premier League with Portsmouth and a loan spell at Burnley, but the striker is hoping to prove that he is good enough to play in the top flight of English football.
