Guys you are missing his main point.Yes ball is round and these things could happen in football, but opponent manager is not on the match. I am guessing he made necessary tactical changes in the game, according to game flow. His opponent doesn't make any changes as tactical wise or subsitutional wise, but the opponent wins the game anyway.

If he is not very unskilful manager, his changes and the preparation should make difference. He should have made all the wrong changes, or the match engine is not responding to his changes at all.
