Given that both Greece and Russia were tied on 4 points, with Russia having +2 goal difference and Greece having +0, why did Greece finish higher than Russia (and thus progress to the knock-out stages) in the group in Euro 2012?
Country W D L GD Pts
Czech Rep. 2 0 1 -1 6
Greece 1 1 1 0 4
Russia 1 1 1 2 4
Poland 0 2 1 -1 2
This question seems to indicate Russia should be favoured over Greece (and this is what I thought was the case as well?)
