Unai Emery has demanded improvement from his Paris Saint-Germain side after the Ligue 1 champions stuttered to a 2-1 victory over lowly Nancy.

First-half strikes from Lucas Moura and Edinson Cavani were enough to seal the points on Saturday, though Alou Diarra's second-half header had pulled Nancy right back into the contest.

And though Emery was delighted with a victory which sees PSG move into second, he acknowledged that his side's performances must be more consistent.

"We are happy with the three points but after that we must learn from this game," Emery, who has been under some pressure following PSG's indifferent start to the campaign, told Canal+.

"We started the game well and scored two goals. When the opposing team pressed up, it became more difficult and it is an issue for the future because the two halves of the match were different.

"I think the team worked very well together to make a good defensive work, but we need to improve when opponents put on the pressure."

PSG face Basle in the Champions League in midweek, before facing Marseille in La Classique.
