The are exceptions when a club is struggling or gets relegated, but how often does young, exciting, English talent swap between premiership clubs?
Lozowski might be 1 such person, Tommy Taylor another. Maybe Devoto.
But it's not a common thing. The closest you get is someone who wasn't getting time at one club, who then flourishes in another environment. Like when we previously signed Varndell, Flutey or Sackey.
But again, it's not very common.
I don't think you can build a transfer policy around signing exciting players from other premiership clubs because they're likely to be expensive and it's a small pool of players.
For EQP players, the most likely way in is either signing from the championship, but there's no guarantee they can make the step up.
Or bringing someone through from the academy, but that's not an easy transition, and requires that the young players in the academy are genuine talents, rather than someone who just looks good in flashes against other young players
It's certainly not an easy job, and I'm glad it's not me that has to do it as it seems you're likely to fail more often than succeed
