You are right in many things especially about Lewandowski who didn't really show what all fans was expecting because of the new game play that Xavi created and actually was the old game play of Barcelona. When Xavi was playing with Iniesta, Messi and Touré. Quick passes and dangerous attackers such Eto'o. So that's why Barcelona really need to bring an attacker that can score in one touch.
Talking about the whole team stats we can say that Barcelona upgraded a lot and playing much better than the past season. They are in their way to find the key.
Barcelona really struggled to penetrate Cadiz's defense in that match, but Barcelona had a good performance. Xavi couldn't lead Barcelona on the sidelines because he received a red card in the first game, but I think Óscar Hernández did a good job.
That match was a bit different from the previous one, of course regarding Oscar's line-up. De Jong, who basically played as a midfielder, actually played as a defender throughout the match, he even played very well there and managed to be the best player in that match. Barcelona managed to break the deadlock after Pedri took advantage of Gundogan's assist perfectly, while Ferran with his solo run also succeeded in tricking Conan in the minute of injury time.
