I have worked on a tactic for the past 2 weeks and I think I've finally nailed it, works well with City, Real Madrid, Spurs, Liverpool and Dortmund.
These are the roles you have to give each player:
Goalkeeper: SWEEPER KEEPER & SUPPORT
Left Back & Right Back: FULL BACK & ATTACK
Central Defender: CENTRAL DEFENDER & DEFEND
Defensive Midfielder: DEEP LYING PLAYMAKER & SUPPORT
Central Midfielder: BOX TO BOX MIDFIELDER & SUPPORT
AMCL: WINGER & SUPPORT
AMC: TREQUARTISTA & ATTACK
AMCR: INSIDE FORWARD & ATTACK
ST: POACHER & ATTACK
With City, the tactic would be set out as the usual back 4 + keeper with Yaya playing the deep lying playmaker role and De Jong as the box to box midfielder, Tevez on the right, Balotelli on the left, Silva in the middle and Dzeko up front.
