Needing a tactic for Man City please!

I'm Man City and I've just won the prem playing a 4-3-3, but only by a point above Newcastle!

I lost the first two games that season (United & Stoke) as well as dropping silly points here and there. I've just signed Neymar, Adam Johnson, Valerio Verre, Alexandre Lacazette, Leighton Baines and I've just lost the charity shield to Chelsea and my first league game to Liverpool.

Any ideas would be great thank you.

You can see that starting XI and also who I've got chilling on the bench etc.
