The Foxes were dumped out of the Europa League in dramatic fashion, losing 3-2 to Napoli before Legia Warsaw missed a last-minute penalty which would've sent Leicester through during their defeat to Spartak Moscow.
Having finished third in Group C, Brendan Rodgers' men will now compete in February's Europa Conference League play-offs against the second-place teams from the competition, which could include Tottenham.
And following the defeat to Napoli, Rodgers insists he didn't even consider the prospect of failing to qualify for the knockout stages of the Europa League.
Asked if winning the Europa Conference League was now the priority, Rodgers told BT Sport: "I've got to be honest, I don't even know what the competition is.
"In all fairness, I was focused on the Europa League and winning this group, or at the very least finishing second, so with all due respect to the competition, I'm not sure what it is. But I'm sure I will find out soon enough."
On another sub-par display, particularly in defence, Rodgers called out his team's naivety.
He said: "I think there's loads of naivety in our team, a lot of young players, and obviously there has been a bigger demand for them this season.
"We've played a number of systems and shapes and individually it comes down to being able to have that mentality to track a runner or go with a runner or stop a cross.
"But it is my responsibility to find that solution. Tonight I felt we were good offensively but it's nowhere near good enough.
"I said to the players 'if we can just tighten up the gaps and do the other side of the game - do more to blocks shots and be more aggressive'.
"We've got to do more.
"For the third goal, you have got to track the runner and if you do then you stop the cross. It is the basics of the game that we aren't doing so well.
"I'm delighted for Kiernan because he has come into the team and done very, very well. For the likes of him, it is a new experience and playing against a really good side.
"But we have given away really cheap goals.
"We had big chances as well - the chance for James (Maddison) straight after their third goal is a huge chance and we're also disappointed with other opportunities, but ultimately we didn't defend well enough."
