Prime Barcelona would dominate this game
Sevilla is in good form, but come on, they are nowhere near good enough to be a problem for prime Barcelona.
Change Pedri and De Jong (two of our best players atm according to this forum?) for Xavi and Iniesta and you would see 70/30 possession, Alba and Firpo pushing forward as much as they wanted, and Busquets+CBs intercepting hopeless Sevilla balls and restarting attacks. Griezmann and Dembele (and Messi) are also very much to blame, but I think a large part of the problem lies in the midfielders being too free to roam and not connecting well enough.
Today Pedri looked tired, lost the ball quite a few times unnecessarily, didn't win the ball when he could. I don't think he should be singled out as the worst player, but he had a pretty bad game, and Barcelona should rely on their midfielders.
