I think that Liverpool will definitely not give Arsenal the satisfaction of winning on Anfield and will try to humiliate them further by betting them in the last match between them his season, so we wont see youth player or rotation player. Liverpool will give them hell on home ground and complicate there Champions League position.
Liverpool no longer need to win in the Premier League because Liverpool have won the Premier League trophy this season. And even if Arsenal loses this week's match at Liverpool's home, it will not affect Arsenal because the Arsenal team will also qualify for the Champions League next season. Because Arsenal is still in second place in the Premier League standings, Arsenal's chances of qualifying for the Champions League next season are still very, very safe and will not be disturbed by other teams because there are five teams from the Premier League that will qualify for the Champions League next season and one more is from the team that won the Europa League this season.
Although Liverpool not winning is also not a problem for the trophy but in the end they will try to win in this match. Do not forget the prestige when the rivalry is always very big then it is certain that when the two clubs meet then it is certain that victory is a thing that must be maintained to maintain the dignity of the club because of the great rivalry.
Currently the trophy is secured but the match in the big match like now is more than that where it is not only about the trophy but also about the prestige that must be bet until the end. So by looking at this I'm pretty sure both clubs will go all out in this match because after all it's not just about 3 points but there is something else bigger than that.
I expect an interesting match and not monotonous for one side because this is a big match with many great players taking part.
You are right, there is prestige and rivalry that will make this match exciting to look forward to. I do not agree if the match is considered like a training for some of Liverpool's non-regular players, Arne Slot must give his best to maintain his good record this season in the Premier League. Arsenal will certainly be favored to win because they are aiming for a safe position, while Liverpool will try to maintain their record.
This game would not be exciting if Arne Slot only played second string players from the start, but if he starts all his main players from the start, then the game will be really interesting. I expect Arsenal to win, but Liverpool certainly do not want to lose and a draw is a possibility for this game.
