Manchester United is just a little better than Chelsea. I can't call that inconsistency because for a team to be inconsistent, they have to be good at times. Manchester United have been poor too. They couldn't qualify out of a group with Copenhagen and Galatasaray. That's not inconsistency, that's bad.
For this season, I don't think they'll be back to any good form. Maybe they may get a little better but they will not be good enough to make it to the top 6. Their problems is not a problem that can be fixed within w short period.
I think Manchester United and Chelsea are just equal because there performance are actually the same and they are very inconsistent in times of wining because the reason why I said they are equal is that the kind of energy and performance they put on there match against Manchester City on that faithful day, that made them to draw the match, so perhaps I doubt of Manchester United would pulled the same performance Chelsea did on that match because it doesn't take Manchester City time to win Manchester United but whenever Manchester City meet Chelsea is always difficult for them to win Chelsea, so that's why I believe there both strength are just equal, I no that the last time Manchester United and Chelsea meet it was not favourable for Chelsea and they lose against Manchester United but still I believe there performance is still equal.
