I don't think that it's worth it. By buying back a player you lose the 6000 and then he will only sell for 80 something percent instead of the initial 97%. Have you actually tried this or were you just guessing? Also I don't even look at the manage my team page when looking for players. I search them up on the TL. Maybe other people are different though.
