Nigeria international, Kelechi Iheanacho, made his mark when he came on as a second-half substitute to play his first competitive match since May.
Iheanacho scored his first goal since September 2018 when he made his first appearance in the 2019-20 season as a substitute in Leicester City’s 4-0 win over Luton Town.
The 22-year-old was introduced as a 71st-minute substitute and helped the Foxes advance into the fourth round of the League Cup on Tuesday.
Demarai Gray opened the scoring with a close-range finish after a well worked corner routine involving Marc Albrighton and Ayoze Perez.
And with the hosts – who had made 10 changes of their own from the 3-0 loss to Hull on Saturday – failing to find any fluency, defender James Justin doubled Leicester’s lead on his return to Kenilworth Road after his summer move.
The 21-year-old, making his debut for the visitors, superbly dispatched a half-volley from eight yards after being picked out by Youri Tielemans’ diagonal ball.
Tielemans volleyed in Leicester’s third goal from substitute Kelechi Iheanacho’s cross.
Nigeria forward Iheanacho then rounded off the scoring late on to ensure the three-time winners progressed with the minimum of fuss.
