Complete frauds don't win 3 straight Champions League titles.
Though he shouldn't have gone back.
Maybe calling him a complete fraud is a bit over the top, but really they were already the finished article and just needed someone with a stature grand enough to manage the egos. Zidane fit this mould perfectly. The team could basically pick and play itself, so flushed with talent it was. It’s not totally unusual for a team that’s already set and established to produce great things, Chelsea reached a CL final under Avram Grant and won it under Di Matteo. I’m not saying you don’t need a head coach, but it’s interesting to see how far you can get with a team of highly driven and talented winners.
