You are right because Aston Villa will only face Sheffield United team which is at the bottom of the standings so the difficulties faced will be very minimal and Aston Villa getting 3 points is like a certainty in this match unless they are too euphoric because they will have the opportunity to get first place in the standings for a while if Liverpool vs Arsenal ended in a draw.
However, my prediction is that the Liverpool vs Arsenal match will not end in a draw, both teams will try to get 3 points and Liverpool has a better chance of getting 3 points because in the last few meetings, Arsenal have never managed to beat Liverpool at Anfield and so far Liverpool have not lost at home because the worst result they achieved at Anfield was a draw, but with the opportunity to take over the standings wide open, Liverpool will make the most of this.
