The Foxes may have got off to a brilliant start in the Premier League, but Ranieri insists there are still areas in which they need to improve.
One of those is ensuring that they start sharper than they have been doing. Leicester have gone behind in their last three Premier League matches, and Ranieri insists that his team cannot continue to give opponents a head start if they want to maintain their fine run of form.
"Three times we go down, that is not good. I prefer to stay up one or two nil," he said. "I don't want to go up 1-0 then after 1-1 or 1-2. I prefer to be losing then at the end of the match win. That is clear.
"It is also important to say: 'Hey, be careful. Three times down is not so good."
Despite these concerns, Ranieri's start at the King Power Stadium could hardly have gone much better.
The Midlands outfit are currently in second place in the Premier League standings, having gone undefeated through their first give games of the new campaign.
A come-from-behind victory against Aston Villa in their latest match means that they go into their weekend contest with Stoke City with momentum firmly on their side.
The same cannot be said for the Potters, though. Mark Hughes' men have been in disappointing form so far, and they are still looking to celebrate their first victory of the season, after what has been a uncharacteristically poor start.
