Here we go again..
Lets look back at the last edition of the Euro Cup. There were quite a few one-sided matches. A few examples are here:
Spain vs Slovakia (5-0)
Denmark vs Wales (4-0)
England vs Ukraine (4-0)
Denmark vs Russia (4-1)
One-sided matches can occur even when the top-10 teams play against each other. So it is not a valid reason not to increase the number of participants.
Yeah, but that's 4 out of 51 matches that was played in the whole competition. That's not much (less than 10%). And in the World Cup last year there were 64 games played and about 5 or 6 of them ended with big goal difference. That's OK too. And how do you expect that nations who are not that strong will end up against strong nations? There probably will be few surprises but most of the games will be a one way street where a one team will attack and the other will defend. Is that a game that you will enjoy watching?
