Championship leaders Leicester extended their unbeaten run in all competitions to 17 games with victory over Watford at Vicarage Road.
Patson Daka opened the scoring with a penalty early in the first half.
And when Ricardo Pereira struck after the break, Enzo Maresca's side looked to be cruising.
Emmanuel Dennis' first goal since his return to Watford set up an exciting finish, but Leicester held on to maintain their 11-point advantage at the top of the table.
The Foxes took the lead after 11 minutes from the penalty spot after Dennis Praet was chopped down in the area by Giorgi Chakvetadze.
