Lets put this into prespective, we have a team that is almost there for promotion to the premiership, this could be the season, this could be the season that the club potential invest £23million, now if you were Allam, would you be putting your money and time into someone like Barmby who has no experience what so ever in a managerial job and still trust us to get promotion? would you be willing to take that chance? No. So, there is your answer
That's why I cant see them bringing Joyce in as manager, and he certainly wouldn't come to be a number 2. With nick I could see him being a number 2 to learn his trade but will a manager in the Ilk of mclaren or jones accept barmby as his immediate number 2, I suspect they would want their own staff.
