I dont think there's a great cohesion between Aguero and our midfielders,there's often a large gap between midfield and attack with Aguero playing more as an individual.It showed the difference when Jesus was on the field,movement and work rate improved,we looked to have a better understanding,and we looked far more threatening as a unit.
In short,our blend isn't quite right.
As much as I hate to say it I agree and it begs the question if we should cash out on Aguero. I love the guy but if a swap could be done with Griezmann.....
