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.
Too early? With the current conditions? I don't think so.
Arsenal may play well but it also won't have much impact as long as Liverpool are consistent with what they are doing in terms of performance because for now the problem lies not only in what Arsenal can do but who can stop Liverpool in a few times because indirectly if you want another club to win (Arsenal) then it is clear that in the remaining matches this sat which only leaves 9 matches for Liverpool and 10 for Arsenal then Liverpool must lose 5 times in those 9 matches and Arsenal must be able to manage to get a win at the same time.
It is difficult because although the chance is still there but it is clearly not an easy thing especially for now Liverpool will definitely focus on the EPL after they were eliminated from the Champions League.
