Miss 3 penaltys? I guess a chines betting company bought your striker, fire him.
With luck like that you was not suppose to win.

But i think you lost because you played defensive and pressure to whole pitch make your team very tired.

You have better team and you beat him on his stadium, you should not set up your team after him then, it is him that need to set up his team after you. You should have played like you did in your first game, maybe even more offensive since you now had the home game.
