The Foxes boss believes the Lions' fighting spirit was a decisive factor in their FA Cup fifth round win over the reigning Premier League champions
Claudio Ranieri has urged Leicester City to heed the example set by Millwall's "gladiators" in the League One side's stunning FA Cup triumph over the Premier League champions.
The Foxes were dumped out of the competition by the 10-man Lions, with Shaun Cummings' last-gasp goal the difference at The Den.
It provided a new low point in Leicester's poor campaign, which sees them fighting for top-flight survival.
Ranieri fears his side have lost the fighting spirit that underpinned last season's remarkable title triumph and called on his players to learn lessons from Millwall's resilience.
