Nottingham Forest vs Liverpool
Man City vs Man Utd
Sheff Utd vs Arsenal
Will any of the 3 title challengers drop points this weekend?
Unlikely but this is the PL, nothing is too predictable.
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.
