there are a few depends on the team you have, most tactics about at the min, are 'score more than you' rather than mourinho bus and 1-0 wins. there is a 4141 that is pretty solid so far, and a couple of possession based 451's (tesla i think the name was).
There are prob 3 you should check out, they won the league in season one for Saints, Leicester and Palace. just search the club names should be at the top with a fair few pages.
