From a neutral point of view, I think you're looking at 3rd place minimum - you've bought very well in this transfer window and I can see Torres getting back to the way he was when he was playing for us. Man City haven't done anything in the transfer window yet (I don't think they necessarily need to).
United's only major signing so far is Kagawa... And whilst a good player he is, I'm not sure that it adds anything other than depth to their team unless they do a bit of a formation change.
Arsenal have to date strengthened... But RVP is probably heading off and IMO Giroud + Podolski < RVP.
Spurs are due to lose Modric, and for now we're not even in the running as a top club at present. All in all, you're the only top club making any moves in transfers, still time yet I suppose.
I can see you finishing above Arsenal and Spurs this season, United and City are going to be a little harder to breach but anything can happen.
