I also voted top 4, but that is just my natural optimism. Realistically, if we get in one or two decent signings, and the core of the squad remains the same. I think we'll do similarly to this year. Maybe if things go our way, that would mean an Europa League spot, but overall, I think United, City, Chelsea and Arsenal will all strengthen; Liverpool and Spurs (if they manage to keep Bale), will also probable do similar, so I think we will struggle to get that CL place.
I can see two mini leagues forming: United, City, Chelsea and Arsenal fighting for top four positions, Us , Liverpool and Spurs fighting for the best of the rest positions.
