Leicester City edged past the Football League’s bottom club Gillingham in the FA Cup third round at Priestfield Stadium.
The Foxes were limited in chances and frustrated in the first half by a well-organised Gillingham side.
They started the second half brighter and found the opening through Kelechi Iheanacho, who managed to fire home Kasey McAteer’s drilled cross.
The draw for the fourth round takes place on 8 January at 16:05 GMT.
Leicester travel to Newcastle on Tuesday for a Carabao Cup quarter-final and Iheanacho told BBC Sport that Saturday’s result will boost confidence.
“Obviously, this will give us momentum to go to the next cup competition,” said the Nigeria forward.
“We are playing Newcastle and it’s revenge for us as they beat us [3-0] in the Premier League, so it’s not going to be easy but fingers crossed, we will fight to our last breath to make sure we win.”
Leicester arrived at League Two Gillingham after a disappointing run of three consecutive defeats in the Premier League.
In blustery conditions, Jamie Vardy was the first to test Gills goalkeeper Jake Turner inside five minutes, but the 23-year-old blocked the striker’s attempt to the delight of the home fans.
