My prediction is
Portsmouth vs Arsenal 1-3
Portsmouth will be struggling with the on-form Arsenal team who
looks very sharp against Villa. I expect them a strong resistant
from the home side,but Arsenal will end up being
victorious.
Man Utd vs Wigan 0-2
Man Utd, this team is sheer lucky with some of the games, and
its time to end their luck. Good luck Wigan, hopefully they will
hit them on the counter and score 2 goals that will shock the home
fans.
