Paris Saint-Germain boss Carlo Ancelotti has warned his players that their recent slump could return if they do not remain focused on the task ahead.
Recent victories over Porto and Evian ended a run of just three wins in eight matches, but the former Chelsea manager has insisted that "a difficult time can still happen".
"We have shown a good reaction after the defeat to Nice. We won against Porto and had a good game against Evian. Things are good right now," he told RMC Sport.
"But the Valenciennes match will be difficult, and the Lyon match on Sunday too. It will be a tough week for us. But the team is in a good form.
"I know football very well. A difficult time can still happen. We must not forget what happened during the match against Saint-Etienne, Nice and Rennes. But the attitude we showed in the last two games we have not shown before. It can help us to overcome difficult times."
PSG are currently second in Ligue 1 with 29 points.
