In all honesty, I have no issue if we don't get a marquee signing. Park, Evra, Vidic, Chicharito, Smalling - all fairly cheap. We tend to get really good results out of those that cost us less than £10m. So if we can, by all means, sign another unknown, Fergie!
For what it's worth, Jones is capable of playing in midfield and did so for many games last season (or so I'm told by a Blackburn fan). I imagine he is our Hargo replacement more than a Brown replacement, but you never know until SAF starts playing him in games. We definitely need a creative player to be brought in, though. I'm not sure we need two - Cleverley will likely take on the Gibson role and from what little I've seen, he's definitely better, more tricks and dribbling in his game, and still creative. Then there's that criminal Morrison guy who is supposedly amazing, but will probably only feature in the odd Carling Cup game. Still, we'll have to see how things go. There's a lot of summer to come yet.
