This match will definitely create high tension because both teams want to get a good result but in my opinion Liverpool is a strong team in attack while Arsenal is a strong team in defense so I don't think there will be many goals in this match even though both teams are dominant in attack but if the defense is equally strong there will be only a few goals and only one will win, I think Liverpool has the advantage because they are playing at home which of course will be more confident.
Yes, that is one of them, self-confidence is the first thing needed when facing an opponent in a match, especially at home, because it will have a positive impact, as well as Liverpool with predictions that they will be superior in their match against Arsenal. Based on these considerations and several things about them when they meet several times last season, but everything can change depending on their readiness in the match.
