I am not sure that Lewandowski will get a lot of chances next season if he doesn't score a proper number of goals. It will also depend on their activity in the transfer market. But his star isn't rising anymore to say the least. He has his qualities, but speed is a big question in my opinion, I like how he plays and he can play a good style within teams that suit him, but I am not sure that Barcelona is still the style he can benefit from. They are more about a high technique level and speed and Lewandowski is getting older and slower. The next season might be the one where he realizes that he is probably sitting more on the bench than getting time on the pitch.
The club's current financial crises I don't think will permit them to sign a striker that'll be able to challenge Robert Lewandowski for the teams regular shirt next season so I think it's safe to say that we're still going to witness another season that the Poland international will remain as the club manager's first choice
