The temptation for the FGR managerial role would be several things.
Firstly it seems that the chairman/owner seems to back the manager as they've all seemed to have done well.
Secondly as a club they appear to be at their Zenith therefore who ever takes over will be in a win win situation. If they bomb it would be as expected so no blame would be attached, if they succeed they become great footballing stock.
Thirdly it gives the manager / IB the chance to ply their trade at a higher level testing their footballing credentials
Hopefully he will stay as potentially we are the bigger club and given time he could be challenging himself at a higher level with us...!
