Because after scoring against us at the Withdean in 2010, he ran the length of the South Stand giving it a big "f*ck you all" with various hand gestures included. He hadn't even had stick from the fans, although to be fair Harding had, so he could maybe have confused it as being for him, or just been sticking up for his mate.
Having said that, there's some selective quoting on here - NSC is split on his return with plenty (including me) happy to see him come back. We're overflowing with midfielders now so I'm not certain he's going to play every week, but he's good enough for a Championship team aiming for promotion, and Gus thinks he's good enough for us, so that's good enough for me.
(Yes, yes, we're failing to keep up etc etc...)
