Well, I've peaked in my FM career.
The story behind it - my first season as CF America (MEX), and I've been doing insanely well despite constant injury problems. In the semi final first leg of the cup, I get smashed 4-0 away to Queretaro, basically giving up hope on winning the cup. So, for [feces] and giggles, I make
this tactic. 4-2-4 set by default to Overload, ridiculously high defensive line and constant closing down, and an emphasis on getting the ball in the box. If I'm out of the competition, I might as well go out in a blaze of goal-scoring glory, right?
In front of a packed stadium at home in the second leg, I instead make history. After passionately demanding that my players take revenge for the last match, the brilliant player and current love of my life Darwin Quintero smashes a volley from 20 yards out in the third minute, setting off a chain of events which I could never have envisioned. They don't just look for goals, they dominate the match. I had a couple scares with close chances in the first half, but besides that, the ball didn't even touch my half in any highlights. I keep raining shots on their net, with 16 total shots taken by the half, 3 resulting in goals.
Going in 3-0 up at half, many would switch back to a more "standard" tactic, try to net two more and solidifying the defense. "[Screw] that", I think aloud, and continue to urge on the players. And they deliver. Goal after goal after goal hits the back of the opposition's net, my defenders putting in their best display of the season as they sweep up any chances before they get too close. The wingers and strikers who cut them up last match were comprehensively shut down as my players walked away with double the opposition's score in an 8-4 aggregate win, headed on to the cup finals.
