Numerous things many already mentioned and just sheer practice.
One thing not mentioned that I have seen is that we improved in the second half of last season. I think this was in part a pick up in Aguero's play. Jesus made a difference straight away and Aguero saw that he was going to have to work with Pep and started doing far more ff the ball particularly coming deep to create the extra man before rejoining the attack when we work it out from the back, something we have improved at hugely with confidence and a great 'keeper.
