PSG, who had not won for three league matches, were booed by the crowd when they reached halftime with only a one-goal advantage after Maxwell had benefited from a brilliant Zlatan Ibrahimovic run to open the scoring.
The home side, however, were far from brilliant, surrendering possession to second-from-bottom Troyes and allowing the visitors to take control.
"It is bizarre but the fans do what they want," keeper Salvatore Sirigu told reporters.
"But we cannot attack all the time. We are not Barca."
"We were not planning to play too high [on the pitch] because we had played on Wednesday and returned only on Thursday," the Italian told reporters.
"It's not enough [recuperation] to have enough energy. That is why we opted to bank on counter-attacks. It was planned. I did not want the team to put too much intensity into the game."
"Ibra is the most important element in the team," Ancelotti said, stating the obvious.
"But we must not think we can always rely on him to win matches. There should be a team behind him."
"He must continue to work to improve his fitness," Ancelotti said of the Argentine who joined in 2011 for a 42 million euro transfer fee from Palermo.
"We don't have yet the playing identity which will give us continuity in the results," added Ancelotti.
