It's obviously so close that it could go any way. But looking at remaining games:
- None of the three play each other
- All three play both Villa and Spurs, one away and one home, and all three also play Wolves.
As for the three botton feeders, Arsenal plays Luton (H), Liverpool plays Sheffield United (H), City plays Luton (H). So that's more or less equal.
Beyond that Liverpool has United (A) and West Ham (A) as the most difficult fixtures.
City has Brighton (A) and West Ham (A).
Arsenal has United (A), Brighton (A) and Chelsea (H).
Everything else is Fulham or worse.
That seems the easiest for City, worst for Arsenal, no? But it's not a big difference in the quality of opposition.
