The politics of succession are delicate: how many veterans can you cull in one go? An experienced player who loses his place to a younger rival is unlikely to forget or forgive; 15 years later he’ll probably still be doing bitter interviews about how your training sessions were basic and the step-up to international level was too much for a manager of your pedigree.
