I think struggle to make the top 8 is a barmy shout jacko - there is no way a side who won the league last year will drop below the likes of Swansea, Southampton, Everton or Cardiff.
You may however have a shout there about the top 4 or 5. Man City and Chelsea look stronger than last year while Man Utd maybe look weaker and without Alex Fergsuon. Then you have Tottenham who have made som incredible signings and well as Arsenal who, although have had a bad summer, do still have Wenger and now one of the worlds best footballers in Mesut Ozil.
That alone could see them out of the top 4, however they then have a rejuvenated Liverpool to contend with who still have Suarez and Agger, and now have the likes if Coutinho, Aspas, Sturridge, Moses and Alberto in the team, without including their defensive signings Ilori and Sakho.
This really ould be the year when Man Utd fall away from everyone else, however I think they should be okay for the top 4 as long as they do not lose Van Persie. Injury to him however and they are in serious trouble.
