Thanks for information. There is a clear difference in qualities. Sometimes average qualities cannot reflect the difference.

In such case, my strategy is always trying to lower the score in the matches, and then try to steal for victory late in the match so that the opponent has no time to revenge. I usually use very defensive formation according to my players available e.g. 5-4-1, 4-5-1, 4-1-4-1, 4-2-3w-1, and even non-symmetric formations. Keep patience until "suitable time" time, and then try to attack. The suitable time is dependent on a lot of factors. If my team losses some early goals, the suitable time come earlier. But I don't mean start attacking when the team concede a goal. Your opponent has no full back and weaker in the wing. I suggest to use some MR/ML/AMR/AML. But defense is still more important on starting the match. If you can identify one or two of opponents' key player, you may put more players around him.

I don't know if the strategy is good but I seldom suffer big losses if I well prepared. Hope these can help you a little bit. I think I The chance for winning is still small. Keep patient and wish for good luck.
