Spain, Germany, Brazil and France are all seasoned winners when it comes to the world cup and I believe this year's own will be no different. I also have faith that Portugal can do something this time around and trust that Ronaldo along with his comrades will do something special.
Spain had been impressive in previous years and no doubt will be do their best to carry this year's cup.
Ukraine will have a lot on their plate when they meet Scotland as they are still being distracted by the war, but I believe they will be worthy opponents for Scotland even if it won't be on their soil.
I don't know exactly the composition of the Ukrainian national team for the upcoming game, but I can assume that most of the players will be from the European championships, which means that the players will be in a normal physical condition, at least not worse than the players from the Scottish team. As for the psychological state, I think the war will affect someone as an additional motivator, and for someone it will be like extra pressure. This is individual.
