To be fair it could very well be because of the team as well, Lewandowski is not playing just 1v1 football on some street, its 11v11 and maybe the team is not giving him the balls that he needs. When you do not pass to a player like him properly, then you end up with a bad result from him, he can't give you the goals you need if you just make him find the score himself, you need to pass him at the right time which is a team thing. I believe that he has done wonderful last year because they really relied on him last year, but this season they are playing other players that can score too, which results with those players trying to shoot more often, and gives him less passes he can finish.
A striker must be able to put himself in the right position so that he can get the ball from another player to score a goal and this type of striker usually really depends on the performance of the midfielders and the support of the wingers. Barcelona have good resources in midfield and the wings should not make it difficult for Lewandowski to score goals. There are times when players miss the best moment to score a goal and that is why football is about collectivity not about one person, so that when the striker is unable to score a goal there are other players who can take that role.Barcelona has always failed to qualify for the group phase in the last two seasons, or more precisely when Lionel Messi left Camp Nou, so Xavi was asked to focus more on overcoming this problem so as not to fail again. This season, Barcelona has confirmed that they will qualify for the next round even though there is still one match left in the group phase and this is what the management and fans hope for.
