If the chances for win are accurate (from the Premier League on Google), which are as follows for each of the three:
Liverpool: 63%
Man City: 77%
Arsenal: 83%
Then it's actually more likely than not, that at least one of these three won't win their game (around 60% probability).
Of course, it's hard to put an accurate number on sports events, it's all just estimates mostly based on previous results.
I am not very sure of the level of accuracy of the percentage because it could have been before the season ended the third performance of the club that competed for the title to experience a setback. I also do not really understand whether it is a percentage of champion opportunities or not, but if seen from various aspects we can see Manchester City and Liverpool should have a greater percentage than Arsenal. The reason is clear that Manchester City has proven it in the previous season and Liverpool are far more prepared at the top of the standings compared to Arsenal.
Another possibility could have happened because the English League is difficult to predict and many surprises occur beyond estimates, but my beliefs still have high hopes for Manchester City because it is far more prepared to come out as the English league champion this season. Although Liverpool or Arsenal also have the same opportunity and I only make predictions individually.
