There was an occasion in the first half where Bernard had the ball, when Digne didn't make the overlap run, and DCL was running from the other corner of the box man in front goal side. It looked like he was pointing to the near post and make a run there but he actually stops his run near enough on the penalty spot. He hadn't even managed to get in front of the defender either.
His movement inside the box is terrible. He can run into channels, which anyone can do, but him running into channels to pick up the ball is useless when we have no one else close to him or able to link up with him.
