in theory yes, but when you’re a club that relies solely on free agents, and on the face of this season incredibly cheap free agents, it is hard to make a case for it being a worthwhile use of a wage. If the new owner wants to come in and spend then there will be more place for a deeper recruitment department.
So you want to sign players based purely on trials or watching a couple of games?
There's a reason clubs study so in depth. Even with this we will not be as in depth as the likes of Peterborough id imagine (forget prem). I use Peterborough as they are the prime example of a lower league club signing young players and selling on for big money
