Aguero or Jesus don't create those chances, so they certainly don't score them. Maybe they score different chances, but anyone who thinks Jesus and Aguero have not had games where they missed a couple of sitters is a completely delusional, Jesus is in shit form infront of goal especially.
Guardiola put out a team that was more than good enough to win yesterday, and should have won by 3 or 4 goals.
It's not his fault players who've been scoring goals all season suddenly missed. I wonder if you were slagging off Pep for starting Sterling and Gundogan at half time?
