How many players of the Ukrainian team have been inactive? Surely there are quite a few that play in other European top leagues? It is true that all those things will affect Ukraine's performance, but Scotland is no unbeatable opponent either. I think both teams have a fair chance to progress into the final qualification game. Odds for progression are currently at Scotland 1.6 and Ukraine 2.2, so roughly 60-40 in favor of Scotland.
For me its realistic that any of this teams wins. Even with Ukraine being in war it shouldnt effect that much the football team maybe it should even give them a boost. If they call players that havent been effected by the war and were playing they should have a good chance
Both countries that is in war is even trying to participate for the contest, i know that if any country defeat them they will use what is happening as point of excuses and for me even though their is no offence for them not participate my suggestion is that they would have contested because of the war, nobody that the home is on fire that feel relaxed and free minded, this alone will make them to fail for the contest because they not relaxed, that is my peace of advice and contribution
