The Foxes take on the Champions League finalists this Saturday at Wembley in the FA Cup final.
It's Leicester's first appearance in the final since 1969 in which they narrowly lost 1-0 to Manchester City.
Leicester have never won the FA cup after losing four finals, three of which came in the 1960s.
Chelsea on the other hand have won eight, with six of those cup wins all coming post-2000.
Kelechi Iheanacho loves the FA Cup
Kelechi Iheanacho is the top scorer this season in the competition with four goals and he also holds the record for most FA cup goals scored as an African, after surpassing Didier Drogba with 14 goals.
The former Manchester City wonderkid told BT Sport: “I think FA Cup loves me and I love the FA Cup.”
His fine vain of goalscoring form since February has seen him become Leicester's top scorer this season with 18 goals in all competitions. With Jamie Vardy often turning provider for Iheanacho, the duo have formed one of the most prolific partnerships in Europe.
Iheanacho has found the net 10 times in his last 10 games in which in that period he picked up the Premier League player of the month award for March.
If Leicester are to win, there is no doubt the forward will be heavily responsible given the hot-streak he is on, so it will be a tough task for the Chelsea defence to keep him quiet.
Kante vs Ndidi battle
In 2016, Ngolo Kante won the Premier League with Leicester City and then made the switch to Chelsea in a £32 million deal. This left a massive hole in the midfield for Leicester until Wilfred Ndidi joined from Genk in the following January for £17 million.
That £17 million now arguably looks like one of the best buys in the last decade with the Nigerian constantly top of the charts for most interceptions. The defensive midfielder has certainly made himself one of the worlds best in that role and he has been a crucial part of Leicester's team.
Kante has had a resurgence in form since Tuchel has come in. The Frenchmen won back to back man of the match awards in the two legs against Real Madrid in the semi-finals of the Champions league. His position under Tuchel has slightly differed which has had a huge impact on his form.
That will be the key battle to look out for on Saturday evening with the two clashing in midfield and both looking to make key interceptions. The game will be won and lost in the midfield so it is vital from a Leicester view point that Youri Tielemans dictates the tempo well.
The favourites will of course be Chelsea given they are the Champions League finalists, however, Leicester do sit in third, a place above them in the Premier League.
Since Tuchel has took over the Blues have only lost three in 25 games winning 17 of those. Their defence has majorly improved only conceding 12 goals.
Leicester have already beaten Chelsea this season, however, that was when Frank Lampard was still in charge so inevitably this game will be a lot tougher for the Foxes.
Score Prediction: 1-1, Leicester to win on penalties.
