Title says it all really. With it being FA Cup Third round day today, the idea of this thread came to mind. I've seen similar ones around before, but not for a while. In all the years we've been playing Football Manager, what are the biggest shocks/upsets you've seen in game? Or even been a part of yourself.
It can be a cup winner, a cup game, a league title, a surprise transfer move, anything!
Personally, I don't have all that many shocks in my time, other than Swansea winning the FA Cup final against Tottenham on FM11, of course Swansea were still in the Championship at that time. In the same season, Tottenham won the Premier League too. Other than that, I've not come across too many, or if I have I've forgotten them.
