I guess Lewandowski would be a good fit for Barcelona. Despite being a really typical offender, he also has the quality to hold, defend, and distribute the ball in a very smart and game opening way. That fits Barcelona's style well although they are already quite different from what they are used to be years ago in terms of ball possession.
Lewandowski is probably the right player for the Barcelona team. And he will be able to adapt himself to the Barcelona team very much. But it is not certain whether Lewandowski will join the Barcelona squad. He may even be with Bayern Munich next season. If that happens then Lewandowski is unlikely to be seen in a Barcelona jersey.
