I'll respectfully disagree.
We need a DOF that can handle scouting and player recruitment. Football is moving away from the setup where managers are the key decision makers involved in transfers. Because 99% of managers don't have the time to also be that heavily involved in scouting.
Our best recruiting years under Poch was when Mitchell was here who understood Poch's system and knew what Poch wanted and needed and could deliver that, and all Poch had to do was say "sure, let's go for that one".
Our years post Mitchell may have been more successful on the pitch, but that is in part because a lot of the squad that Mitchell put together is still here. Players bought after he left have all either been square pegs for round holes, or round pegs but not the correct size for the hole so to speak.
In modern football, the most successful teams tend to be the ones with a sporting director pulling the strings, and a manager that can focus on the on pitch work as much as possible.
If Spurs want long term success and stability this is a model that the club will have to give in to.
Ah I miss Paul Mitchell, found us some great talent.
I also remember an interview he gave a year or so later where he said that behind the scenes at Tottenham were an absolute mess.
As fans, we're not privy to certain information, and over the years there's always been things coming out at that no one is willing to fully discuss at the club.
