As mentioned in the other Commoli thread, this is destined to fail as no Premier league manager has ever liked losing control of recruiting. Look at Fergie and Wenger, they don't have a Director in their clubs in charge of recruiting or 'football strategy'.
This appointment, imo, is purely for commercial reasons. And that is to spot young talent, sign them, let them spend a couple of years in Liverpool or on loan, then sell them on for a profit. Like a cattle market.....whether it is good or bad, i think we have to look at the Ramos era with Director of football, and after when Harry took full control.
I don't doubt the commercial side of this appointment but I do feel it may not fit in with the traditional Premier League Management style.
