People who are saying that Souness doesn't give youth a chance are just spouting rubbish.
Gallagher may be out of favour now, but he was brought through by Souness, same with McEvely, Dunn, Douglas and Danns. It's crucial that youth players are brought in at the right time, not too soon so that they don't have their confidence smashed, and not too late so that you can get them in the team for as long as possible. So far I think Souness hasn't really lost marks concerning younger players, his selection policy at the moment is odd, but not because he isn't adding young players to it.
