It is going to be a massive gamble whoever comes in. Whatever your thoughts on moyes, to get someone in who will almost guarantee top 6/7 finishes and great pound for pound signings will be very hard.
I'm not saying I'm for a internal appointment because I'm not but what they lack in managerial experience they make up for in knowing the club, the players, the transfer targets, the training ect ect....
With a foreigner what they lack in the above they would hopefully make up for in tactical nouce, different methods, and a big factor IMO keeping the current players on their toes wanting to impress.
It could go right or wrong which ever way you go, which I find the worrying thing and tbf to BK I don't envy his posistion having to get it right!
Think what needs to be remembered is were not broke, we don't need fixing....but as with any servicing a few tweaks here and there in the right places would be much welcome!
