I'm gonna stick my neck out and say it's between Shelvey and Ben Arfa (second part of his spell here).

I liked Shelvey to begin with, but I don't think he was ever all that. The flash passes and spending most games looking around and being late for every defensive action frustrated me. I loved Ben Arfa and remember him fondly - I also seem to remember him being a player who didn't put in the effort when things weren't going our way.

Feel free to agree or disagree. Who else was a lazy old git?
