Just an idea...
In real life, when a manager moves clubs he usually takes a team of people with him, e.g. assisstant manager, coaches etc.
We have seen this recently with Fabio Capello and his "Italian Team". Also, Steve Bruce and Eric Black joining Wigan from Birmingham.
My thought is that this option could be included in the negotiations when approached to manage a club and be an important function for changing clubs.
Don't know if this has been discussed before but have been thinking about it for a while. What does everybody think?
