It's also nonsense, Pep generally plays possession football but at home to Barca last season we played counter attacking football.
So far under Pep we have played 4-3-3, 3-4-3 and 3-5-2 so we don't play one way.
The biggest reason we have struggled in the big matches (Spurs away apart) is our utter wastefulness in front of goal, Chelsea at home, Liverpool at home, Spurs at home, Everton at home all defined by missed chances by us. This season already we have missed 6 big chances.
Guardiola believes the best way to beat most teams is to ensure they don't have the ball. We are inot there yet but what is letting us down time and again is our finishing (Jesus missed a few against Brighton and Bournemouth, Aguero missed chances against Brighton, Silva and Sterling missed sitters against Everton.
We will no doubt get chances on Saturday but so will Liverpool as they attack at pace and in numbers. The winning side will be the one who takes their chances.
