Liverpool will actually win the Premier League trophy this season. Currently they are at the top and leading with 15 points, which is enough. There is not any team in the Premier League that can surpass them in points, so this season the Premier League trophy is for Liverpool. Obviously they cannot put more effort than before into the Premier League because that is their main target for now, and I know they will go towards it.
It's too early, in my opinion, to say that Liverpool will win the Premier League this year. Football is a circle, therefore anything may happen at any time. Forget that they are at the top of the standings, leading by the bigger amount of points. These 15 points are sufficient for the squad you're hoping will be the one that doesn't dominate the league.
Because you never know what Arsenal will come up with in their remaining matches, given that they have almost 10 more to play, I expect them to produce a positive outcome in those matches; you can simply make an early prediction because Liverpool is leading the tournament.
