Not getting wins when the opponent quits

It is very frustrating and you definitely should get the win. 

One thing that winds me up is the massive difference in ability between a 4.5 star and a 5 star team.  It is pretty unrealistic.  I play as my favourite team (4.5 star), so many people play as Real, PSG or Liverpool, you'd think that only their supporters play the game. 

Anyway when I do quit, it's because the gulf in class between the 2 teams is so wide, it's not worth playing (maybe I'm just not as good as I think I am, but on the rare occasions I manage to connect to someone who has also chosen a team that's a similar standard to mine, the game is much more competitive).
