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.

Liverpool only need 3 more wins to secure the EPL title, the number of points collected by Liverpool is certain to be impossible for Arsenal to catch up with even if they manage to collect all the remaining points. Now Liverpool chances are getting bigger because they have the opportunity to widen the gap with Arsenal to 13 points if they can win over West Ham.
There is no hope for Arsenal in the EPL, they have to focus more on the second leg of UCL, they only need a draw to qualify for the semifinals.
