When this tournament is used as a place to try strategies for big teams, then at least they can still play with good results. Because trying several strategies doesn't have to mean they always fail because the opponent is a weaker team, even though it's good for mediocre teams but that doesn't mean they can win easily. But yes, there is nothing more that can be done because everything has happened, I just find it difficult to accept the results obtained in this National League because as a big team of course they have several advantages even though they are trying a strategy at least they can still survive better because they have a squad with better quality.
Of course they could end up winning, there is no guarantee that it will be a loss, it just means that it is not going to be that easy to win when you are playing with some players who are not your regular starters, with a system that you are trying brand new.
Just like everyone else said, this is just a friendly thing, and it's going to be quite difficult to predict what the big nations would do. Sure the opponents are weak, but usually the huge nations do not face with teams like sri lanka neither, maybe a few games like that, but some tough opponents as well. Hence why the results are almost always unknown, and whoever finds a good strategy, they may win.
