1-1 its just finished.
But we are now above Aston Villa. So, considering Wigan play Villa final day, even if Wigan beat Arsenal we cant finish below Villa and Wigan this season now. Wigan would be on 38 points if they beat Arsenal. So if they draw they would either go down or beat Villa and be on 41 points with Villa being in the bottom 3 (unless Sunderland lose on the final day).
