Best tactic I've used so far, here's the results for my Cambridge United:
26 played, 20 wins, 5 draws, 1 loss, for: 58 against: 15
Ended up 2nd in the league behind man city. Won the league cup and the europa league. My only loss came to Man Utd in the last game of the season, with unfit players having played Chelsea 2 days previously and secured 2nd place already.
I've used Defensive Positioning as the focus and 30% Match Training. Also put all the long shots to rarely and I've never used any Opposition Instructions.
Got my first Champions League Campaign next year and will be strengthening the side to push for the title and get to the further stages of the Champions League.
Great work!
