Ranieri has conceded that complacency played a part in Monaco's second-half collapse, but chose to focus on the positives as his side made it 10 games unbeaten on their return to the top flight.
He told Ligue 1's official website: "Am I angry? No. Football is a marvellous sport. We scored two beautiful goals very quickly and then we lost our concentration, but Sochaux played as I expected them to."
When asked if falling from top spot was a source of frustration, the Italian replied: "No, it is not a problem. We just need to improve from match to match.
"We never let up physically, but we maybe allowed ourselves to believe that the match was finished after we scored our second goal."
Paris Saint-Germain now lead the way in Ligue 1, sitting two points ahead of Monaco.
