I don't know who they look at next.
Taking Dibling as an example, this is their best opportunity to get the highest price possible. As time presses on, he gets closer to his contract end and his value decreases. He doesn't play, or just dials it it, his value decreases. There's a small window for them to get top dollar.
I hate the way that the window means certain clubs have to play chicken with their first few games of the season; but as we get closer to the window more players will be agitating for moves. Players who we may have enquired about earlier in the summer may become available, or may consider Everton as an option. Other transfers will affect club's desire or need to sell. Other transfers may make certain players available. This is why so much is done late on in the window. We're digging through the yellow stickered food shelves come deadline day unfortunately because we don't have the draw or the capital to move quickly.
