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. 
I dont think any suprises is gonna happen again with the winner of the league this season because it's just remaining an official match that would crown Liverpool champions and the reason why I say this because even the only team that would have probably cause them problem is far behind which would have been Manchester city because arsenal currently have more bigger fish to fry which is the champions league.
