Isco is pure class and we could do with him as a squad rotation option, but we don't necessarily need him. There is no guarantee that we need him just because when Mata doesn't play we don't seem to have a brain in attack. I'd rather look internally and try to sort something different out e.g. playing Hazard at no. 10 or something before we spend money on another player in the -3-. The "we look poor without Mata so let's buy another no. 10 just for the few games so we can rest Mata" excuse doesn't do it for me IMO. People are forgetting we're potentially bringing in the likes of KDB next season, plus the fact that someone like Oscar and Marin still haven't exactly settled in as well as Hazard has. Once again, I really, really rate Isco, he's a joy to watch, but I don't think he's necessarily needed. I know he's coming at a cheap price but like people have said, it's not exactly needed. Need is a hyperbole.
