The Italian coach was not too disappointed as he believes that this campaign was a positive experience, with the club entering the Champions League next season
The French capital club defeated Lorient 2-1 in their final league match, but still finished second as Montpellier disposed of Auxerre 2-1 to finish three points clear at the top.
Ancelotti took positives from PSG's campaign in the league and noted that it will allow the club to compete in the Champions League next season.
"Congratulations to Montpellier," he told Canal +. "We had a good season, but we missed a little something to win the title.
"It is a good experience for the future. We have to look for the future with confidence.
"Second place is not bad because it qualifies us for the Champions League. What we have done this season will be useful for the next one."
