They won against Liverpool and everybody knows that Liverpool is in pretty bad shape right now even Manchester United was able to dominate them so yeah there isnt anything special about this. I'd love to watch Arsenal play against some other top teams right now to convince me that they have a shot on the top spot otherwise its pretty unconvincing though
Actually in this match I didn't see Liverpool bad because despite their defeat they still played very well although there were still some mistakes especially for their defense which always failed to mark the players from Arsenal but they were able to even equalize twice.
But Saka's penalty broke the mood and they couldn't keep up.
Liverpool did lose 3-2 to Arsenal but their performance in this match was no less good than Arsenal's. Even though the performances of Luiz Dias and Salah did not look optimal but overall Liverpool can play at the same level as Arsenal. The match between Arsenal and Liverpool should have ended with the score 3-3 from my point of view because Liverpool should have also got a penalty when Magalhaes was seen for handball in the 14th minute but the referee thought that it was not a foul.
