Top 8 is realistic. I think that the Manc clubs, ourselvse, Chelsea, Arsenal and Spurs will all finish above them. Beyond that, I can't see many better teams in the PL.
Everton have had a decent start and I suspect will do well enough. I think Villa could have a good year too. Beyond that, no-one is really standing out.
I said this in the Southmapton pre-match thread but was ignored/called overly negative. Southmapton have a good side and a good manager. A combination of talented home-grown players and some strong signings has given them a nice balance. They play good football and are a cut above most Premiership clubs.
Schneiderlin, Lovren, Ramirez (though off form), Wanyama, Osvaldo, Lallana and Shaw are all quality players, and distributed neatly around the first team. Davis, Clyne, Lambert, Rodriguez, Ward-Prowse and Cork are all good players to play around them. Perhaps not the best squad depth, but they're a good side.
