The link between them is what seems to be a stubbornness to try something different, as you quite rightly say Glasner has more experience, so hopefully he will realise that the current squad is not suitable to 3-4-2-1, and adapt accordingly.Actually no I didn't. I admit to thinking he was a breath of fresh air when he first arrived and I'll also admit to feeling his sacking was sooner than expected but that was before I learned how divisive he was in the dressing room and how destructive his presence was becoming. Vieira did an ok job. Nothing more.
Not too sure why you ask that question though. Two completely different managers and styles. One has achieved little, the other is only in his early 50s and has already taken 3 unfancied teams into either the top 4 or winning a European competition or both. You cannot compare Vieira to Glasner. Still not even sure why you brought him up tbh.
