Since i was with bad results in the last games. I started testing this and i will give you guys the result:
LAST 4 GAMES WITH ME AND 3 FRIENDS SUPPORTING MY TEAM (+14% Possession):
Statistics:
1 Win
1 Draw
2 Losses
7 Goals Scored
7 Goals Conceded
LAST 4 GAMES WITHOUT ME AND ANY FRIEND SUPPORTING MY TEAM (+0% Possession):
Statistics:
4 Wins
21 Goals Scored
0 Goals Conceded
If you can see as well, in the CUP, with more 14% possession i lost 2-4 at home, and i gave up watching the second leg..So i won 0-3 away lool
