Indeed it was embarrassing, but that's what you call you preparation, I really cant remember the last manager who looked into this much detail for us. Of course theres the other side of the coin which is overprep that can backfire, but for a crucial match you'd really want to study the opponents just as well, even if they are the easiest side in the draw. Afterall and unlike a league in CL its tiny individual moments that make the big difference. Allegri always learned on the Fly, always kept things simple and to an extent it worked, of course organisation was the biggest key, it actually puts fear in the opposition, because now you are just a pain in the ass to break. That said i feel especially nowadays you just gotta be a little more street smart and have quality especially in CL, quality we wont short of, noone can argue Mbemba an ex newcastle player and Sergio Oliveria an ex nantes player both nobodies are any way better than our players. Yet they was trained and prepared and of course motivated. Not sure where our motivation went for the first half, we really did approach it like a final.
As for the Motto, its a great point honestly, we can change a logo, for marketing, then why cant we change a motto and the words we use the language and vocab in around the whole club. Psychology plays a big part here, words, make thoughts, thoughts make beliefs. It's them beliefs we carry to our CL match, putting pressure on ourselves ' its the only thing that matters, do or die, now or never' yada yada.
Changing motto is a sensitive subject because its all we've been and one could argue why now, but I think its predated, football has moved on, we need something more relevant, before it was making the means end, now its more. Boniperti came out with it, but if we had an equally as great legend in Del Piero coming out with a Motto, im sure it will be easily accepted.
