I don't see the problem...

look;
lost from team -15Q-jor-14-temp-5-lunes-20-5-2013-22222.jpg

1st, for the 11 players under the field, the differance is not+15Q for you... sure no? maybe a 38-39Q vs 47-48Q
There are lots of factors in a result, for example the game never select all players to be mentioned in comments of the game, or just to be active and effective.
Too I can say for experience that one can have 1/2 of the team of 1* and just 3-4 players of 5-6* and win against a team full of 4-5* players, just because the 1* are well proggrammed, so, I'm not surprised...
Too the game proggramm matches to make you do some decisions, like do a substitution of 1 or 2 players that today are invisible or fail all.... game do the things to make you work...

And that's what happen mate, and lots of more things...
