From ones who haven't so far been mentioned, I'd say Michael Ball, Felipe Caicedo, Paul Bosvelt, Adevayor, and David Sommeil. I kinda liked Jo as well, even though he was terrible most of the time.
Is Hamann classed as 'obvious'?
Others would be Trabelsi, Mpenza, Petrov, Reyna, Musampa. As for Fernandes, loved his enthusiasm, in his first season he looked like he had a bright future, but he fell away badly in the second.
