#2 Celta could not trouble Barcelona's porous backline
Barcelona have conceded 15 goals in 12 league games this season. Their defence is not the best one by a long distance. The likes of Gerard Pique and Nelson Semedo have failed to impress so far. Sergio Busquets also can't cope with pace in midfield, but Celta failed to test these weaknesses.
They had just 31% possession in the game and Barca did a good job of making most of it harmless. Celta had six shots in the entire game, but only two of them were inside the box. Even those two were from tight angles and did not pose much threat.
Barcelona faced Slavia in their last game who did a great job of exposing those weaknesses. Celta had the likes of Pione Sisto and Iago Aspas to trouble Barca, but they failed to do so. A more aggressive game plan could have paid dividends.
