I see the league being extremely competetive next year. Ofcourse, there are lots of factors to play out before the start of the season with the transfer window still yet to finish playing its part, but I actually don't think there is alot in it between the Top 6 sides next year. I see Man Utd, Chelsea and City finishing in the Top 3 spots (although, perhaps not as comfortably as some people would have you believe) but I wouldn't dare guess a 4th placed finisher right now, which suggests that I see Liverpool being more than capable of finishing in the Top 4 this coming season.
Man United and Chelsea
I certainly don't see Liverpool finishing above these two sides, and having read the comments of the thread, you all seem to follow that same sentiment. United are just far too strong at home, teams turning up to the 'Swamp' already admitting defeat and the way they regularly turn the 'lesser' sides over with ease. This will always stand them in good stead. Chelsea will no doubt spend money and add to an already strong side, I expect we will see a better Torres this coming season, too. I see these two finishing in the Top 3, no questions.
Man City (I'm a City fan)
Perhaps the hardest to predict, but I definatly see City joining the above two sides in the Top 3. While City take stick for having a negative style of play, the side will be strong next year with or without Tevez. This will be the first summer at City you won't see an overhaul of players, and that will only help the side gel further. Despite no expected overhaul, you know players are going to arrive at the club, Aguero? Nasri? Being linked with the top players and you wouldn't at all be suprised to see them roll up at City. Again though, it comes down to the way City can put away the 'lesser' sides. City held the best record for points against the bottom half of the table last year, along with one hell of a strong defence. If a few more creative players turn up at the Etihad stadium, I think City will challenge on all fronts.
Liverpool, Spurs and Arsenal
I can't look beyond these 3 sides for the fourth spot, but between them its incredibly difficult to decide. Both Spurs and Arsenal are set to lose key players or retain unhappy players, and that is always going to take its toll. Unlike City, you don't see Arsenal or Spurs replacing Modric or Fabregas with top class replacements. I actually think the momentum is with Liverpool, but I don't think the back-end of last year with Kenny is a clear indication of how this season will go, the pressure was off then, it was a breathe of fresh air the club needed, but now its a different ball game. Okay, Liverpool haven't been signing superstars, but they have been signing solid, premiership proven talent in key area's (You've needed a winger for years) Regardless of last years performance, Liverpool are a good side, and I can definatly see them challenging for a CL spot next year.
