Leicester’s Nigeria internationals, Wilfred Ndidi and Kelechi Iheanacho both started on the bench for Leicester in what was described as a routine win over Championship side, Wigan athletic.
Iheanacho stayed on the bench throughout but Wilfred Ndidi was substituted for Nampalys Mendy in the 77th minute of the match.
An own goal from Latics debutant Tom Pearce and a deflected effort from Harvey Barnes gave the Foxes, second in the Premier League, a 2-0 home victory.
“We didn’t play particularly well and we need to be better,” said Rodgers.
“Defensively we were good but offensively we were too static.”
Leicester picked up their third successive victory in eight days and Rodgers added: “The players gave everything and I couldn’t fault the mentality of the team – as always it was top class – but we demand more quality.”
The Latics, who won the cup in 2013, fell behind when Pearce scored an own goal, steering the ball past team-mate David Marshall.
Barnes had an effort well saved before he added a second, although his strike went in off Wigan’s Cheyenne Dunkley.
Leicester could have scored a third but an unmarked Dennis Praet headed wide.
Wigan substitute Jamal Lowe thought he had pulled one back when he volleyed in but it was ruled out after a check from the video assistant referee showed there had been an offside earlier in the move.
