Things like this happen. I lost my 2nd Round Cup tie this season after I lost my 1st Leg 1-3 at Home, but I came back in the 2nd and Won 3-1. However, as we were tied 4-4 on Aggregate, Extra Time was needed to get a winner. Unfortunately for me, it was the opposition who got lucky, and in the 115th min of ET scored and won 5-4 on Aggregate. Sure, I still won 3-2, and I was clearly the more dominant team, but the opposition got lucky and were able to win. The player that scored the winner; that was his first shot on goal in the game and it was his first ever goal in the Cup, as far as his Statistics are concerned. Something similar happened a few games later. I was playing a Champions League Group Game the other day and I had a 5-1 lead in the 70th min. Within 10 mins, the opponent scored 3 times. Even though they had fewer chances and were of lower quality, they still managed to rifle in 3 goals, one after the other, with no problem. This really annoyed me, as this should never have happened, as my Keeper is 51 and his players weren't even 45. Yes, I still won 5-4, but these things happen in real life too. I'm not sure if you watch the English Premier League, but last season, Crystal Palace came back from being 3-0 down at HT, and drew 3-3 with Liverpool. In 2005, Liverpool did the same thing against AC Milan in the Champions League Final; 3-0 down at HT, drew 3-3 and won on Penalties. My point is, things like this happen and while it does indeed suck, there's nothing you can do about it, upsets are a part of Football, you just got to accept that and move on.
