Minutes for changed players

[xingular]

This is not fair-play.

I need a win for 3 goals in semifinals. I scored 3 goals. The other team injured a player of my team. The change for another player cost me 6 minutes! In this 6 minutes the other team has scored one goal. Just the necesary.
I have all the posession and all the attack EXCEPT IN THIS 6 MINUTES.

And OF COURSE, no red card when in a fault one player goes injured. I've never see one.
I have more: this player injured, has one goal and one assist in this match and he gaves only a qualification of 5!

This is not real, this is unfair. No, I disappoint with this ****. 6 minutes for a change of players. And all the semifinal goes wrong.
