As I remember any superstar forward who joined this team played very well and in and there they had shining days here Lewandowski is just one of them and that's maybe all because of the team tactic they have in Barcelona where they have midfielders supplying the forwards perfectly, also after Xavi joined this team they are playing perfectly and you can easily see that on the results they get, that's why they are on the top of the table currently.
Strategy and squad depth are the most supporting reasons to get good results in every match.
Barcelona have had what was expected this season, they have had good performances from goalkeeper, defender, midfield and forward and that makes them the favorites to win the title.
I know they are not completely stable yet, but they are very lucky to be able to lead the standings with an 8 point advantage over Real Madrid (if Barcelona wins today's match). They still have to ensure victory from every match, including today, of course. That will make Barcelona able to keep a safe distance from its toughest competitor as long as possible. Barcelona against Cadiz today, I hope it's an easy match but they are missing Pedri and Araujo and Dembele. Pedri and Dembele were injured, while Araujo received a disciplinary point due to a yellow card.
