It's more about practices than individuals. We need to cut back what we offer the fringe a bit. Take Smith Rowe: due to injury trouble he was only on about £70k. Given his immense talent, finding him a fair move wasn't hard.
Here's Fulham's current wage table, give or take (Palhinha's off):

A year ago we handed Nelson a weekly wage of £100k per week, which is ahead of every Fulham player. Even at West Ham who've been sniffing round, Nelson would be about top five, on par with an effective specialist like Ward-Prowse. Nelson's on what Xhaka's on at Leverkusen.
We don't build the profile of an Arsenal fringe player after his early 20s, we bench him. So the smooth liquidation of any fringe player's paper "retained value" requires paying him wages in line with what he'd be offered by the type of club that would actually want to sign him right now, today.
