Brendan Rodgers said he does not "even know" what the Europa Conference League is after his Leicester side were demoted to the competition following their 3-2 Europa League defeat at Napoli.
The Foxes had started Thursday in pole position to advance but were made to pay for their slack defending as the hosts progressed at their expense in a dramatic climax to Group C.
Leicester drop into the knockout play-offs of European club football's third-tier tournament in February. The draw takes place on Monday and they will face one of the runners-up from the group stages of the Europa Conference League.
