Leicester boss Claudio Ranieri has told his fringe players they blew their chance after the Foxes suffered a record Champions League defeat.
They were hammered 5-0 in Porto on Wednesday to suffer the biggest defeat by an English side in the competition.
Andre Silva scored twice while Jesus Corona, Yacine Brahimi and Diogo Jota all netted as the Foxes were dismantled, with Ranieri making 10 changes and picking a second string.
Leicester had already won Group G and, after leaving stars like Jamie Vardy and Riyad Mahrez at home, Ranieri - who gave goalkeeper Ben Hamer his first start for almost two years - said they failed to impress.
