To be fair, it is only since the latest patch. They somehow "fixed" things that make Lewa nearly useless for scoring. As you said, he cannot contain the ball and his shots are slow and aimless which was really outstanding before the patch. Now the defenders are always winning against him. Given that he was never a fast breakthrough kind of player, but man his shots were a guaranteed goal.
Before the patch he was up there on average goals per game with NIF Werner in my team. Werner is still around a 1 goal per match after the patch because he is fast, but Lewa instantly fell below 0.7 goals per game since the patch and will probably fall further.

The only reason I keep him is that he is still very good as center player for creating chances and assists (for IF Werner now), but finishing with him … is just sad. I still have hope that maybe the next patch changes it again. He is a 89 player for **** sake who will probably be POTM again or have another inform next week the way he is doing in the Bundesliga. Who needs a Team of the Year or Team of the Season Lewa if he gets one when he is just not usable in the game.
