I've had no trouble with my city team im 5 points off top and in 3rd half way through my first season, I just whent for the attacking 4-4-2 and then put my two wingers into AML & AMR, however I haven't got a tactic against the big teams or a second tactic to confuse the AI, so if you could find a good secondary tactic against harder opposition then you should be flying.
Srna Richards Dunne Bale
Wright-Phillips Hamsik Palombo Petrov
See your team is 5x as advanced as mine, you should do fine with these tactics.
Hope this helps.
