Looking at the most successful coaches in the world (Pep, Klopp, Simeone, Conte and Zidane) they are big/strong personalities. Very charismatic. Do you have to be or has it just helped them reach the top? Not sure.
But it is the biggest question mark relating to Ten Hag. It has been said that talks between Ten Hag and Spurs broke down due issues with communication/language barriers. Even in Holland there has been criticism over him being less «charismatic» or even a bit weird. I think he is just a bit geeky.
I think it could be wise of him to do what Bielsa and Pochettino did; hire an interpreter. I consider myself to be quite decent in English, but I often experience feeling a bit inferior in meetings with people who has english as their first language. Especially if there has been a while since I last spoke. I think I just come across as a bit less intelligent or slow. For a coach, that could undermine his authority.
