Arteta should absolutely be on that list.
Giroud is if anything overrated. There’s a serious lack of perspective with him, and people love to use little stat graphics to lose perspective and hype him up, not to mention the aesthetic quality of some of his goals also helps him. Finally people like yourself go to a lot of effort to go against so called ‘Giroud hate’ which just ends up in people over-adjusting in the wrong direction.
Walcott is much more underrated than Giroud, for example. And he definitely should not be on any list with truly–without qualifications–good enough players like Gilberto and Lauren (and Arteta).
