Lionel Messi has not played a single minute this season. Luis Suárez and Ousmane Dembélé have missed a good chunk of it. Barcelona have been forced to give youth players like Carles Pérez and Ansu Fati starts in the forward positions, with Antoine Griezmann moving to different spots along the forward line as needed.
The good news is that this team even without Messi still scores goals. Sure, they were shut out in the league opener, a 1-0 loss to Athletic Bilbao. But since, they have scored a whopping 12 goals in 3 matches since.
