It's the same vacuous argument that was used for LVG and Mourinho, not because they had Prem experience but because they were experienced in managing big egos and winning titles.
Fat lot of good that experience does when you're past your sell by date as a manager. Forget Poch for a minute, the same people making these inane arguments would tell you Bodgers would be a better hire than ETH because of that oh-so-important Prem experience.
Klopp and Pep and Tuchel didn't need it. Granted it took the former 2 a year or so to adapt. So what? They took over patchy squads at Liverpool and City that took a season or two to sort out, as ETH will be taking over a very patchy squad if he comes here.
