Ever had just one of them games? Course you have.
I've been doing pretty poorly in the league at the minute, and just tried out a new formation (4-3-2-1) and my boys were playing some of the best stuff all season. Playing a West Ham side who are storming the league, we were looking likely to come out of it with a draw - which would do the players the world of good in confidence.
Then within the last ten minutes, I had my first choice right back, and my captain & centre back sent off for stupid second yellows, after making all my subs. Then, unsurprisingly conceeded.
FML.
