Hell, that was a somewhat decent post particularly for your standards, but you can always praise the tactics of the winning team because the point of tactics is to score and to win.
WHat really happened is both teams up 3-0 lost the games themselves, though Liverpool more deservedly winners, they were better in both games yes. Tactics have to change when you are down 3-0. Second game Busquets, Rakitic and Vidal were simply very poor... Messi was also poor relative to his standard and should've scored on more than one occasion which would've ended it right there. THe quick corner goal encapsulated entirely the game.
They were brilliant performances both in their own right, but tactics had no more to do with that than any match. They were both indeed miracles, verily. You place too much emphasis on your last ten years of playing Fifa on playstation , which I think it's great someone like you can develop competence, but you've lost the plot. You miss the essence of what is happening on the pitch, and again that is your loss, if you weren't so defensive you could benefit yourself.
