No
Everyone can loose a game from a team like Leicester but I never saw a team like this winning the league or the CH.L.
you are wrong about that .
Ooops, misunderstanding
I was talking about top eleven.
Comparing TE with real football, in the first one you can see many times 6-7* teams loosing from 4-5* teams but never a 4-5* teams to win a league or CH.L. vs 6-7* teams.
About real football, your example with Aston Villa was in different times.
When there was a champion from England, Germany, Italy and Spain as the 4 top dogs (and some outsiders from France, Netherlands, Portugal or Yugoslavia ...).
Now it's a Marathon with at least 8-10 super teams every year.
