Arsenal has been very inconsistent in previous seasons. So with Arsenal, I think nothing is guaranteed. But if you look at the performance of this season, obviously Arsenal is going to be ahead of Liverpool. Everyone thought that Liverpool was going to challenge Manchester City quite well for the title. But right now Liverpool is not even in the equation. Surprisingly Arsenal, who lost the 4th position to Spurs in the last season on the last day, is the first team on the table. So if you just think about the performance of Arsenal this season we will have to say that they are more than capable of beating Liverpool.
On the other hand, Liverpool without Mane and Mane without Liverpool are not doing very well. Some will argue that Mane is doing very well at Bayern Munich. But I beg to differ. But Liverpool without Mane is absolutely dying. So I don't have much expectation in this match against Arsenal from Liverpool, to be honest.
