Just use trial and error. I'd go with a 4-3-3 long balls. You have enough quality there to boss about the midfield with Yaya Touré, Gareth Barry, De Jong. Then you have Balotelli, Tevez and Adebayor upfront, which is potentially two target men and a complete striker. You can't go wrong. But then you'll be neglecting your wingers such as Milner, Adam Johnson and David Silva.
