Zaha's technical ability does look questionable. You can see why he could flourish in the Championship but is he actually even flourishing there? Around ten goals in over 100 appearances compared to Tom Ince who's scored more in about half the other's appearances. The latter seems capable of stringing together some decent passes too. I don't think United will be signing either, but I know who I'd bet on having the better PL career.
We still really, really need to look at CM, but I'm hoping Frogie's interest in Hazard and Moura indicates an acknowledgement that we need more fearsome wide presence.
I want those things too, but I have the suspicion Fergie will put buying another CB in the summer at priority. Rio's got no more than one, or two, or three at maximum, seasons left with us. Vidic is over thirty. And he tried to sign Varane not so long ago. More likely a prospect such as Zouma than someone like Hummels. After that he'll go for a winger. And then, perhaps, a midfielder, but probably for rotation rather than a star name. There's a bunch of talented kids coming through and I only see us trying to replace the Fletcher-that-was with a sizeable transfer, not Scholes. United's squad is definitely missing a ball-winning midfielder, or at least an understudy to Carrick.
