This is one of my fav docs (I've posted the English version in here before but like so much on YouTube looks like it's been pulled).
Anyway, here is a non-English version, it doesn't matter too much as the clip I want to refer to is only short, literally a few seconds and there's no speaking. I have played a few games but it's rare thing that any of my managers have got pre-match stuff right, here Simeone nails it for me. When he was river Manager he had his team warm-up under the stands prior to the Classico away to Bocca. He just paces around between the players, as the clip progresses you can see him talking. Again tiny, tiny thing and maybe it's the film that's atmospheric but I'd want my manager to be with me pre-match like this. (clip is at 1:11:28)
