Saying, oh anyone can go into Bayern or Barça and do well, winning championships, sure one thing is saying its easy, its another to actually go out and get it done, you talk as if they were easy tasks, but if it were the case it wouldn't account for coaches with decent repuations prior such as Klinsmann messing it up so badly.
What would you describe as a special manager? someone who wins the league every season? that constitues all of... Pep and Mourinho and Sir Alex for me, but they're gone and we're not getting them. So instead we speak then of finding the next special manager, well forgive me for saying it's easier said than done and would no doubt require us having to take another risk on an unproven candidate, but hang on, isn't that where we went wrong with Moyes? You could also argue the case Bayern took the risk on an unproven young candidate in Klinsmann who was also seen as a potential up and coming special manager who then went on to fail miserably whereby Bayern then turned to a tried and tested coach who rebuilt the team and had them back as champions soon after.
Sometimes experience is in order, a known quantiy, certainly when a pillar of strength for 26 years at your club is removed and your foundations are looking to be crumbling, it could be said there's a time and place to gamble on an unknown and this isn't one of them.
Then we look at the ideals this club stands for above all else, attacking football, blooding youngsters, being positive in approach, Van Gaal ticks all the boxes (Moyes ticks none) while offering concrete evidence from experience he is a man who can stabalize our club and re-energise our football while following the traditions, not to mention the honours hes racked up, it's still a no brainer for me.
