I dunno how it is in 09 (Lol, Ive changed keepers every season with Blackpool), but what I did in previous versions was that I'd sign my backup on 2 year contracts and release them at the end. I'd give them 2-5 sub appearances in League games and put em in the starting line up in all the cup games (except semis and finals, and European tourneys, of course). They did sulk SOMETIMES but nothing that'd get me irritated.
