It isn't puzzling.
Reserve Team football is a million billion miles away from the Premiership.
And football history is littered with failed internal promotions.
If we were a mid table side, fine, take the gamble, only I still wouldn't see why.
Why not get the BBest we can, instead of someone about whom we know nothing as far as Premiership is involved ?
Didn't Liverpool dominate English & European football for decades by promoting from within?
Yes, that and having oodles of cash. But they were unique, and were specifically geared up by Shankly to work that way.
Why gamble ?
How were they specifically geared up for it, the way Shankley worked? Why can't it work for us? How is it more of a gamble than appointing someone like Sven?
