Liverpool seems to be the team of choice that we're going to compete with, but Chelsea won't have the distractions of last season, united are a bit of an unknown quantity, and I think both Spurs and Arsenal will be a bigger threat than last season.
With Thor and Alverez replacing Sterling and Jesus we'll have to adapt slightly and I wouldn't be surprised if it's even tighter this year.
The World Cup break will also play a part in what will be an exhausting season for many players, especially at the top clubs, and for that reason I think it was the right thing to do to have a "light" pre-season.
