it's not a shame, the biggest teams of Europe had already be beaten 3-0 or 4-0, it's things that happen to every team.
I've not seen your match, but after two goals conceded, your team may have doubt and may thought that now it's finished. So it is often like this, they were K.O. and they conceded more goals. Because they think it's impossible to come back.
And after 1-0 or 2-0, your team take also more risk to come back, and the defense is less compact. And you take more goals. I happen often like this.
