Nobody is a replacement for anybody, we're in a typical Arsenal summer window. It'll be whether we get our targets or not, and whether our contract holdouts force a move or not. AW isn't sitting there doing formation wishlists, he doesn't view anyone as anything other than what they are unto themselves. To some extent, that's one of his strengths. Mostly, though, it's become nothing more than a lack of vision for a team without any real goal or purpose.
