Carlo Ancelotti admits he was "disappointed" in Paris Saint-Germain's inability to hold onto their two-goal lead as St Etienne fought back to claim a 2-2 draw with the Ligue 1 leaders on Sunday.
Javier Pastore's strike and a Zlatan Ibrahimovic penalty put PSG in a commanding position just 20 minutes into the match, but an own goal from defender Alex and a goal to Francois Clerc salvaged a point for the hosts.
Despite the missed opportunity, PSG maintained their five-point lead at the summit of Ligue 1 with second-placed Lyon and third-placed Marseille failing to register wins on the weekend.
Ancelotti was left to rue a lapse in concentration in the second half, but he credited St Etienne for their improved performance.
"I think it's a good result," Ancelotti said. "It's not easy to win away to Saint-Etienne. They are high on confidence at the moment. But we are a little disappointed because we were leading 2-0.
"We played very well in the first half and then things got a little tougher after the break. Perhaps that goal we conceded just before half time turned the game. It became a very physical match after that and we struggled a bit more.
"This is football. The turning point was perhaps the goal that we conceded at the end of the first half. If we'd kept our 2-0 lead, the second half would have been much easier.
"ASSE have a lot of intensity. This is a decent result at this point in the season. The championship is not over. There are still many matches to go. "
PSG defender Christophe Jallet believes his side were undone by their complacency after Ibrahimovic's goal.
"We've got mixed feelings because we were up by two goals and we had the game under control," Jallet said. "We sort of stopped playing and then we started sitting deeper and we handed the confidence back to this Saint-Etienne side.
"They gave it everything and they managed to equalise. But we still added a point to our lead in the standings. But, yes, we are disappointed because we could have had all three points tonight."
