We shouldn't be talking about arsenal wining the premier league title this season because I don't even see any possibility in that, for the fact that liverpool lose against Fulham in thier previous match does not mean that they will continue losing. We should know that losing is very certain so far as football is concern, so don't be surprise to see them wining thier upcoming match. And I know too well that they will struggle so hard to win thier upcoming match, so as to secure thier position with enough point.
Liverpool is leading with 10 points now, it is enough to ensure that Liverpool will stay in the 1st place at the end of the season. Moreover, Arsenal often plays under-performance, they made too many draws. Although Liverpool was just defeated by Fullham, I agree that Arsenal has missed the chance for winning the EPL title. Liverpool must try all out getting points in the next matches. If there is no big change with Liverpool performance, I'm sure Liverpool will be the champion this season. 
Van Dijk came out and compensated for the mistake he made in defense and put Liverpool ahead again. This team does not stop even if they make mistakes, they are very focused to win.
