Paris Saint-Germain winger Lucas Moura has accepted that the side must improve after their 1-1 draw away to Ajax in the Champions League on Wednesday night.

Edinson Cavani's opener was cancelled out by Lasse Schone's second-half free kick and the Amsterdam outfit finished the stronger of the two sides.

Lucas told reporters: "We played against a very strong team, and it was difficult. I think we played well but we must do better.

"With my chance early in the second period, I made a mistake - I hope to score next time. It is difficult to explain why we finished the game in such a complicated manner."

PSG host Barcelona next at the end of the month.
