Liverpool have produced many, many great players over the years and will no doubt continue to do so. In 2009, Tony Evans from The Times, put together a list of what was felt to be Liverpool's greatest 50 players. Much to talk about and debate no doubt. The list is already out of date because there is a fair chance that Luis Suarez will be appearing on the list anytime soon, if not deserving to already.
