True, if your sole focus is on what have they won and where.
We've done that to death, and all it's really done is take us further down the rabbit hole.
I've followed Postecoglou's career since Brisbane Roar. I can't stress enough just how impressive his managerial talent is. Whilst the Australian/Japanese/Scottish are not near the same level as the Prem, it doesn't change the fact that he's taken 'also ran's' and turned them into champions. Everywhere.
He makes teams better, he makes the players in those teams better. He has a 100% record on this, and that is where the focus needs to be.
Denigrating his abilities, because he hasn't done it at the highest level, is arrogance of the highest level. Let's not forget that Wenger was managing in Japan when the filth took him on. Granted he managed Monaco before that, but the French league, at the time, was a poor one. The Portuguese league isn't one of the top leagues in Europe either, 7th in the FIFA rankings. That hasn't stopped Amorim from being on the wishlist of many, nor did it stop Mourinho from developing into one of the best managers in the last 20+ years.
We've had some of the best managers in World Football fail here. To compound that, the Football they've had us playing has made our eyes bleed. Whilst I can't and won't guarantee that he'll make us Champions, I most certainly will guarantee that he'll give us a team that'll play Football we'll all love watching.
I'm nailing my colours to the mast now, I want Postecoglou.
