Lets bring in some more experienced players
I believe that if palace keep buying really young players the side will not pick up. I believe that black and gray will both be good players but not for atleast three seasons and besides if they start looking truly good they will soon be snapped up. Yes palace would make a profit but they would again be in the same situation.
I believe palace should buy some seasoned players who want to move somewhere to play at a high level all the time. Players such as Steve Howey,and Peter Beagrie.
