come on man, are you saying it's a coincidence there was such stark contrast in the game on both sides of the RC? a moment like that carries not only tactical but psychological implications too - Real got a boost and took advantage of the time that ManU needed to adjust to the new reality on the field.
Sure, ManU should be able to do better than conceding 2 goals in 2 min but you can't just scratch up to coincidence that Real were looking 2nd best in every aspect right up to the RC and then all of a sudden were marauding ManU.
