Gerrard should have stayed and retired as a professional as a Red, that debacle in LA was a waste. Aldridge definitely, and the obvious recent ones people have mentioned. This will sound kinda weird, but Friedel. How much did we spend on keepers much worse than him since he left and during the rest of his career. He went on to be quite successful, consistent in the Premiership. Sander wasn't any better or worse than him (as proven by their respective track records after departing LFC), and then came Pegguy, Kirkland, Dudek, Carson, et al....finally stabilised a little with Reina.
