Yeah Lewandowski performance was bad against Getafe, but in this match against Cadiz, he already good enough by giving an assist. Although we know Benzema is really great striker and he many times score hattrick, but he's not always score a goal in every match. There are many matches he performed poor and no give any contribution.
I think as long as Barcelona win the match, it's already enough.
The victory of the team is important, but the striker must also have ambitions, it is clear that scoring goals in every match is not easy, but an assist is a good start. Barcelona with Xavi have become not a very productive team, they are more inclined towards a defensive game and this often affects the fact that the team began to score fewer goals. Lewandowski will try to be top scorer again this season.
