As happens in La Liga, no? Or is it goal difference between the tied teams, there? Either way, their games against each other determine who comes top in a tie.
Yes, to a degree but then Real and Barca(assuming its those two) both have a ridiculously larger number of games to make sure they don't end up drawn, and there are two games, which gives both teams a chance to pull one back in the head to head stakes. Its a much fairer way to do it than head to head in a 3 game league, which is unbelievably stupid of them to do.
Either way, Russia were good for most of the game, horrendously lazy defending in the dying seconds of a half catches out so many players. Though the commentators wanted to put it on the left back it was a CB who randomly ran across missed the header badly and left a gaping hole for the guy to run into.
Manager has to take most of the blame though, 7 shots, 7 misses, very very poor misses in the first game, Pav comes on and in 15 minutes makes the other guy look a joke so who starts and plays most of the second and third games, the same awful striker. If RVP played and missed 11 shots in 11 in the first two games, you would drop him for the third, let alone someone no where near RVP's level. He was out of form and playing badly, ended up with 14 shots and 14 misses, of which half should have been goals from the type of chances missed.
Greece, don't think they were very good but ultimately the team who doesn't turn off for 30 seconds because they think the whistle is going to go for half/full time will have a huge advantage over a team that can't wait to get off the pitch. Russia absolutely threw it away. Poland did to a degree as well, Greece were so horrifically awful in the first half of the first game, they should never have let them back in it at all.
