I maintain that I wouldn't have signed Hutchinson at the price we paid, and it feels like his Joorabchian links are the only reason we did.
Luiz feels different because his Villa track record suggests he is (or can be) a step up from what we have. Zinchenko likewise a no-brainer as long as he's happy to fight for a place.
None of this explains why Nuno, from day 1, allegedly took such a personal dislike to Edu (by most accounts an affable guy who gets along with people - an Arsenal-supporting mate tells me he might if anything be too laid back). But it feels like we might never know the reason, unless there is an autobiography coming.
