Look at Ney's best goalscoring season.

Our playing style was totally different. We used him way more as a finisher than as creator. Nowadays he and Messi have to run the show because the midfield isn't creative. What is more, our pressing doesn't work (do we even have one?) so he has to run longer distances. He starts his dribblings deeper and when he runs forward without the ball, getting assisted by Leo or Suárez, he lacks the necessary freshness in front of the goal. He will never be a clinical finisher like Leo or Suárez, but his finishing is ok as long as he is relaxed.
He still has nearly one scoring point per game, which is ok. I know, he missed a lot chances this season, but he isn't the problem why we won't win a big title this season. Yes, he dribbles too much, but he is forced to do it as Lucho doesn't have a plan. Fix our midfield, become a TEAM again and we will be happy with Ney's performances.
