I doubt Danny is going to pick an inexperienced coach or assistant in this situation. It calls for experience and someone he knows well. Barlow would fit the bill.
I have been on a few coaching sessions given by Frank and he is a very good coach and well regarded in the game. He could do a job for us.
Having thought about it and the possible opptions I think its pretty likely that Frank Barlow will be appointed very soon, possibly this week.
