Lens are succumbing to defeat at the hands of AS Monaco, who lead their Ligue 1 clash 2-0 at the halfway point at the Stade de la Licorne.
The visitors were quickest out of the starting blocks as Anthony Martial was played in by Joao Moutinho, but the teenager fired wide of goal on seven minutes.
Monaco continued to force the issue through chances from Layvin Kurzawa and Geoffrey Kondogbia, with Moutinho pulling the strings in midfield.
Pablo Chavarria fired just wide for Lens in the 35th minute, but Leonardo Jardim's charges were duly rewarded moments later when Yannick Ferreira-Carrasco lashed a powerful shot into the top-left corner.
Monaco then doubled their lead on the stroke of half time when a fast counter-attack led by their Belgian scorer was finished off by Martial's low drive.
