Liverpool have nothing to fight for again, they have been given the premier league trophy already, and they are out of other competitions left, so they are going to play freely against Arsenal, either they win or lose, it’s not really going to add anything to them. Arsenal still need to get a win in the match, if Arsenal cant win the remaining matches which they are having left, then they might not even end the season in top 2 which they are currently in, because Manchester city is currently behind Arsenal, and any mistake from Arsenal then Manchester city will be taking over their current position.
They calculated everything well, and it is now in their favor because they have gathered enough points that they don't need to do too much, and they really put in a lot more energy into the Premier League than the Champions League. Even when they lose against Arsenal, they don't have anything to lose, and this is the opportunity that Arsenal would have used from the beginning of the season, but they were unable to keep up like in the previous seasons. and then their players seem more active. And even Arsenal has given up on itself. Manchester City is far better than Arsenal because we have won a lot more trophies than Arsenal.
Arsenal are out of the Champions League competition so the only thing left for them to do currently is to protect what they've been achieving consistently for years now which is ending the league as runners-up, honestly it thought this was Arsenal's season cause they've been very consistent in qualifying for top four, I won't have believed if anyone had told me that Arsenal wouldn't win any trophy nor the league this season.
What suprised me most is that Manchester City that's been hindering them from winning the Premier league didn't do that this season but they still couldn't seize the opportunity, they allowed Liverpool to win it, maybe Arteta is just too comfortable with finishing the league as runners-up.
