I'm not a great tactician but here are a few hints : Play Richards!! instead of Dunne and set him to "challenge keeper" on corners. Make sure you have corner inswinging. Kompany is not a Midfielder, plus he's very inconsistant. Since you have a really defensive midfield, you can play ron.e's tweaked version (with De Jong DMC). Try to get someone more offensive to replace Kompany (Toulalan, Veloso, Barreto). I'm unsure the tactic works well with a right-footed left winger. Try Sturridge or Petrov there (or buy someone). Make sure you retrain your players for the positions they are playing.
