Every signing that was brought in this summer was given the green light by both manager and DoF.
Every player that we went for and didn't get in was given the green light by both manager and DoF.

It's very simple.
Another remit for the DoF is to, in the long term, look at potential avenues for the club to explore recruitment wise, and open lines of dialouge with clubs.
