Tuchel has enjoyed a superb run since replacing the sacked Frank Lampard in January. The German has led Chelsea to the FA Cup and Champions League finals, while taking them back into the Premier League's top four.
Winning his maiden silverware in English football would be further evidence of Tuchel's impact.
But Leicester, two points above Chelsea in the Premier League, will pose a significant threat to Tuchel's ambitions under the astute guidance of boss Brendan Rodgers.
The Foxes are aiming to win the FA Cup for the first time in their first final appearance since 1969.
No club have appeared in more FA Cup finals without lifting the trophy than Leicester, who have lost four times in the showpiece match.
In contrast, Chelsea have won the FA Cup eight times, with their last victory coming against Manchester United in 2018.
