If you want I can upload my tactic as it has a lot of personal Player instructions that I don?t have time to detail, however its basically Two fullbacks 1 BPD Defend 1 CD Defend, 2 Wide midfielders 1 BWM Defend 1 AP attack, 1 AF Attack 1 CF Support.
Pretty much play narrower, Press more, Push Higher up, Stay on feet, Shorter passing, Wide midfielder swap, more roaming. Starting Strategy Attacking and Very fluid.
Signing wise I didn?t sign anyone till Janujaz in January and Yuri Tielemans but with an end of season transfer date. Second season I got rid of Zabaleta, Clichy, Javi Garcia, Demichelis and Dzeko all of whom largely underperformed. Signed Alex Sandro, Danilo, Mangala and Luis Muriel all so far have proved to be great signings.
One other thing to keep in mind while your tactic is still bedding in keep a 4-2-3-1 Tactic in reserve in case you need to switch to it against the top teams as you may struggle to control the midfield.
Edit bit more info: Managed to get aguero scoring 36 in 45 all comps for me, setting him as the penalty taker will help him pick up vital goals to keep him in form as goaless spells are notouriously hard to recover from on this version. Setting negredo to hold up the Ball, shorter passes and Moving into channels seems to create a lot more chances for the supporting aguero.
The only problem with my tactic i can see is The BWM defensively hes strong but as the tactic plays very much like city in real life he gets a lot of clear shooting opportunitys from the edge of the box when the opposition is totally penned in and rarely scores.
That was my original post
