Question about a Champions League

[Galgo]

Hello fellow managers :-)

I have a question, and maybe someone can help me or advise me. I play level 3 at this moment. Leading, played `16, won 16, 54 goals scored, 8 against. In the cup i was beaten by a level 5 manager, average quality 34,2, mine was during these matches 33,5. First match (home for me) 2-2, second match 1-1. Today i played quarter final Champions League against a level 3 manager. Average quality of him: 25,6. My team is 33,9. He win 0-6, i played at home!

I played my favorite 4-4-2 (DL,DC,DC,DR>DMC,ML,MR,AMC>ST,ST). The strongest players on the field, no injury's, full condition, full morale. He played 4-5-1, midfield with two attacking midfielders. Some of the statistics:
Possesion: 54-46
Shots on goal: 7-7
Corners: 8-6
Saves: 1-3
Tackles: 14-20
Yellow: 2-0
Red: 0-0

Don't get me wrong, i know how to lose...in a game, in life, whatever, and there are more important things in life then winning in Top Eleven. But i don't understand the score, and the fact i had 7 changes, and 0 goals. He had 7 changes and 6 goals, in 16 competition matches i only get 8 goals against. After, i get some points, i go to the selection, and all players had no condition, it was a little bit red. And after 2 seconds, it started to go green. Cheat???
