Nice coach Claude Puel has lamented his side's inability to keep possession as they were beaten 4-0 at Marseille on Friday night.
Puel's team were given a tough night away at the Stade Velodrome, as a brace from Dimitri Payet and goals from Florian Thauvin and Abdel Barrada saw them lose their second game of the season.
"Nothing really went for us tonight, especially their second goal, but we lacked control and gave the ball away too often", he told reporters.
"The second goal should not have been given and we didn't deserve to be two goals down at the break. After that, OM got into their stride. We were always open, we tried to be enterprising but OM were very good."
Nice currently find themselves sitting in 16th place in the Ligue 1 table, on four points.
