This team is in 12th place in the league and they are beating City, who is in 1st place, which is a great luck for Bournemouth, the team they got three points from is the strongest team in the league.
Of the three teams, at least only Liverpool played at home but still, in reality Liverpool fell behind first and even Liverpool lost in the first half with a score of 0-1. I think all of these teams will lose at the same time, but Liverpool still managed to turn things around, maybe also because they played at home and Liverpool managed to win with a score of 2-1.
About Newcastle, although I have previously said that Newcastle is not a completely weak team. But anyway, sof ar this season in my opinion Newcastle is still in a bad trend if I compare it to Newcastle's good results in previous seasons. Thus, I am still confident in Arsenal to win but yes, in reality Arsenal was not able to score at all even though Arsenal basically has good statistics in this match, but Arsenal still lost.
Likewise about the defeat experienced by Manchester City, I think this is a surprising defeat because Bournemouth was also leading 2-0 until Josko Gvardiol finally scored a goal in the 82nd minute and made the final score in this match 2-1. The defeat experienced by Manchester City has now made Liverpool return to the top of the standings.
But about Arsenal, interestingly Arsenal was overtaken by Nottingham who won big 3-0 against West Ham. In addition, if for example Aston Villa and Chelsea win, then Arsenal will be in sixth position. But yes, it seems it will still not be easy for Aston Villa and Chelsea, because they will play against Tottenham and Manchester United.
