Millwall boss Harris predicted Lions would have Leicester's Foxes on the run
Millwall 1 - Leicester City 0
Millwall manager Neil Harris admits he was not surprised his League One side beat Leicester in the FA Cup on Saturday.
The south London club are through to play Tottenham in the last eight, after Shaun Cummings scored a 90th-minute winner to heap more pressure on Leicester boss Claudio Ranieri and his beleaguered side.
Millwall were reduced to 10 men for much of the second half after Jake Cooper was dismissed for his second bookable offence following a rash tackle on Ahmed Musa.
But the deficit only sought to galvanise the League One club, with Cummings cooly scoring the winner for the Lions in the closing stages.
"I think people thought we had a chance, and we did," said Harris. "We assumed Claudio would make changes but the quality of player you are playing against is outstanding.
"We were the underdog. There is no doubting that. We knew we could cause Leicester problems by playing high-tempo, aggressive football.
"Am I surprised we won? I wouldn't say surprised. We knew we would have to catch Leicester cold."
Foxes boss Ranieri has, meanwhile, called for Leicester's "gladiators and soldiers" to step forward and save the club's season.
"I want to speak again with the players and say we have to fight every match," said Rainieri. "'Who wants to fight? Tell me'. I need the soldiers, I need the gladiators, because Millwall, with 10 players, showed they are fantastic gladiators.
"It is strange because last season we won for this, to be more determined than the opponent and play with more heart than the opponent. We could also lose but we would fight every match. I want to see this, the fight until the end. This defeat could be good for us because when you lose against a team who fights, you have to say well done to them but why did we lose?"
