Although the players listed above i coudnt get there deals back I managed to recreate a deal very similer
Player name neil el aynaoui, 21 years old, 4.5 star for my team witha 5 star pot, hes got 5 goals 2 assist in 8 games
I personally offerd him out for a LOW fee of 100k and a buyback of 250k with no expiry
[I think if you offer out young players for very cheap with good POT the clubs are willing to accept a very low buyback because the fact you offerd them out so cheap but this allows me to let them develop at a better club, have there value increase loads and then get them back for e.g 250k ]
How it can be abused
Example if you start out as a small team like SEP in brazil and have future star endrick offer him out for 50k, buy back for 500k and sell him to liverpool let him become a super star and then buy him back for 500k offer the player like 20m signing bonus for a player that might be worth 120m
ive uploaded the game file its called BUY BACK CLAUSE LOW GLITCH FOR SI.fm
