The qualification mode asks for a winner in the match, so if it's a tie after 90min we will see extra time and maybe penalties.
Then the winner will play Wales a couple of days after (in Wales) for one of the last remaining spots in the World Cup.
I think all 3 teams (Scotland, Ukraine, Wales) are almost on the same level, so we will see two very interesting games.
Whichever teams qualifies, they will be in a group with England, USA and Iran and will have a good chance for qualifying to the final round there as USA and Iran are definitely beatable for any of those candidates.
I personally think that Ukraine will win, because they’ll be keen to make a statement for all the people back at home who’re in the middle of the war and what better way to do that then by winning this match, and further I believe that they’ll be able to beat Wales and qualify for the World Cup too. However it’s quiet possible that they maybe emotionally distracted and may not perform to their usual standards, but I’ll yet put my faith in them and I hope that they beat Scotland and Wales.
I don't think Ukraine is going to win. it is one thing to have emotional support for ATM and absolutely another thing to look at it practically. the country is going through a war right now and it is obviously not their first priority to win in the FIFA World Cup. I always think that they will surely try to make a statement for the whole world to see but that is going to be really hard to do.
