Leicester City drew 2-2 with Southampton at the weekend.
Leicester went into the break 2-0 down at St. Mary's, but Ranieri insisted to his players that they should be fearless in the second half.
The Italian boss told his team that he didn't mind if the scoreline got worse, as long as they made sure that they attacked in the second period.
And his message had the desired impact, as it inspired the Foxes to mount a comeback, as they came back to claim a 2-2 draw in the contest.
"We were desperate [in the second half]," Ranieri admitted. "I told the players, 'If we lose 2-0, 3-0, 4-0, it's the same, we're still losing'.
"They believe, our fans believe, and this is very important."
Leicester's draw with Southampton was achieved thanks to two strikes from Jamie Vardy, which have taken his tally to nine goals for the season.
It was another example of the Foxes' never say die attitude, and it means that they have still only lost one game all season.
Leicester are currently in fifth place in the Premier League table, and their next fixture comes at the weekend against Crystal Palace.
