Yeah right it doesn't matter who scores whether it's Lewandowski or anyone else, a club plays with 11 people and everyone has a chance to score goals isn't there even history has seen where a goalkeeper can score goals, so it doesn't matter who scores goals, because the importance of playing solidly with a club can be seen from how compact they are on the field, at least getting victory points.

A club must at least be able to win and get points to secure its position doesn't mean a striker is infertile and can't score goals he can even be a good assist, back to your statement again as long as barcelona can win it's good at least he can get important points to secure a position in LaLiga this season.
