Can't really compare the 2 (or 3) though.
Old man Allam knew absolutely nothing about football (and was a bit of a ****, in relation to our club).
Silly **** Ehab also knew next to nothing about football, but thought & pretended he did, and was a massive **** . )
Neither chose to install a Tan equivalent.
Acun knows a lot about football, being a massive fan and student of the game, having had previous experience, etc. And he's wise enough (although it doesn't really take much wisdom) to have people like Tan around him.
There is however a balance that he needs to be careful to maintain, between being hands on / hands off.
I think KT is spot on saying "Still feel very positive about the direction of the club but it seems to me both Liam and Acun/Tan are still on a steep (& costly*) learning curve". (* added text).
