that's a bit far-fetched. Utd were way behind last season, and arguably they are weaker now than they were last season whilst City and Arsenal are stronger.
A lot rests on Toure. Can he recover, and if not how do we play without him.
When we played at old trafford last time, they won us because they won the battle in the middle and now they have strengtened that unit. Also, they had a good shot at 2nd or 3rd before Carrick got injured. This showed that Carrick was very key to their good run and now they've gone ahead to sign Schneiderlin, a proven premiership DM to ensure they don't have a repeat of loosing ground because one player is out. I earnestly hope you're right but I'm not seeing it now unless we address the CM void.
