Leicester boss Brendan Rodgers believes his side proved they can compete with the best in the Europa League despite blowing a 2-0 lead to draw with Napoli.
Victor Osimhen's second-half double earned the Italians a 2-2 draw to deny the Foxes victory in their opening Group C game.
The striker levelled with three minutes left having pulled a goal back after Ayoze Perez and Harvey Barnes gave Leicester the advantage.
Wilfred Ndidi was also sent off in injury time for a second yellow card to add to the Foxes' woes.
