And the Italian, whose second-string side squeezed past Derby 3-1 after extra time in a fourth-round replay, is prepared to risk seeing the season lurch to a new low by making wholesale changes.
"Never say never, we couldn't win the Premier League could we?!" I just don't buy into the old chestnut that the FA Cup is a welcome distraction from Leicester's travails in the league - this is a team in a bad state despite a 3-1 extra-time success over Derby last week, form which is hardly earth shattering with the Rams conceding seven times at home in two games since!
"We know it will be tough".
"We are the underdogs, if they beat Bournemouth and Watford who are above us in the league".
"Our target is the Premier League - that is it".
"We believe. In this moment we lack confidence but you can get confidence only if you win and play well and we're not in this case". The goal is the Premier League.
"This is a huge game for us, the players and the fans are really looking forward to it but I will admit that my mind has already turned to Chesterfield on Tuesday".
Saturday's game kicks off a crucial 10 days for Leicester, with the Champions League tie at Sevilla on Wednesday followed by the visit of Liverpool in the league next Monday.
Millwall have kept five consecutive clean sheets and it's over eight hours since they conceded a goal. Everything is fantastic (for them). We fought last season, fought this season, and will continue to fight mood will change.
But Ranieri dismissed further fears over his selection and reckons the players he does pick can prove themselves, having reverted back to his first team only for them to lose 2-0 at Swansea on Sunday.
"It's a great opportunity for my players".
The Leicester manager may be short of attacking options, though, with Islam Slimani ruled out and Leonardo Ulloa a doubt. I prefer to take my responsibility.
