Just dont sell any strikers. Becouse when you will buy new one it will be the same. Just play and eventualy will be performing better. Some time ago I was doing the same thing. I was looking at ratings and change "sell-buy" players. That what NORDEUS want. Now im just keeping my players and eventualy they performing better. In my experiance when I sell player that is not performing like they shoud then some other player that has 7-8 now get 5-6. Sell player only when you will by better quality player. This is my advice what will you do is your choise.
