Christophe Galtier insisted he was not worried with Paris Saint-Germain's poor form since the return to action after the World Cup.
Folarin Balogun's last-gasp equaliser for Reims at the Parc des Princes on Sunday left the defending champions with just one win from their past four Ligue 1 matches.
PSG's lead at the summit has been reduced to just three points as a result, a gap that could have been even less had Lens and Marseille not also been held to a draw on Saturday.
Galtier's side have a quick turnaround before Wednesday's trip to Montpellier and he is pushing for a response from his squad.
"Worried no, disappointed yes. We are not going to hide behind the post-World Cup calendar," he said after the match.
"It's been a few weeks since our performances were not at the same level as in the first part of the season. We must work, we must find solutions, and reconnect.
"A crisis of confidence? I don't think so. Maybe a crisis of complacency, all the demands we had.

"It went haywire for different reasons. It's hard to restart. I have high-level players who cannot accept to be at this level since the beginning of 2023."
With just a few days remaining until the mid-season transfer window slams shut, Galtier confirmed the club intend to be active in order to bolster the squad.
"There are 48 hours left. The club is working on the arrival of at least one player. There are significant constraints with financial fair play," he added.
"We want reinforcement. Will it happen? I don't know. We cannot hide behind the absence of a player. We have quality players in the squad. Everyone must find their level very quickly."
