maybe Acun is reluctant to replace his friend Shota as it's Acun buying the players & picking the team & Shota is just a Yes man doing what he's told ?. A new manager is not going to stand for that situation (unless Acun employs another friend)
Interesting take on things and who knows, personally I doubt it. You don't buy a dog and then bark yourself. But hey, nothing would surprise me, what I did find telling was both Acun and Tan sat shaking their heads before leaving 5 mins before the end of the Swansea game, that to me suggests that perhaps it isn't them picking the team.
