But this is my prediction:
Liverpool has been a very hot club since few years ago, Arsenal was not playing good, even to qualify for Champions League became challenging and impossible for Arsenal, even till last season when we thought the club would make the fourth position but unable to. From the head to head, with how strong Liverpool was, it is normal for Liverpool to win Arsenal most often. Even there were many matches played by both clubs that Arsenal was unable to score at all. But this would be deceiving if punters are using previous years matches played between these two clubs to predict who would win. Liverpool has not even won a single away match this year, the club draw more than lose though.
So because of this, either Arsenal wins or draw this matches is what likely going to happen.
A draw would be more likely with betting odds of 3.80 although head to head is different and I think Arsenal this season is better than last season and vice versa with Liverpool who are on a decline but it's not that they will be weak no, same thing both teams will be stronger tonight.
It will be a little different from last season for Arsenal, maybe you could say they are more consistent with the game and some changes in players that are more improved compared to last season, so I assume Liverpool's opponents will be equally strong for both but Arsenal have the confidence to play in this match. Emirates Stadium even if Liverpool play more dominant I don't think Arsenal will lose in that case, so it's possible that a draw will happen so I choose that betting opportunity.
