It looks like Eddie Nketiah still needs stronger chemistry and bonds between players, he performed quite well in his two matches with The Gunners. unfortunately, Nketiah was unable to take advantage of the opportunities he had to convert them into goals during the Newcastle match. I'm pretty sure, Nketiah can be relied on on the front lines of The Gunners in the future. at least, Nketiah still needs time to become a sharp sticker.
When you think he has played well and understands the strategy, then the chemistry between the players should also be good. I think Eddie Nketiah's failure to take advantage of all the scoring opportunities has nothing to do with bad relations between the players, that's normal in my opinion and every player can always fail to take advantage of goal opportunities. The problem is in his finishing, and it just needs to improve as he gets more minutes.
I remain optimistic that the Gunners' young squad will continue their positive trend to widen the gap between the points with Manchester City.
I think your optimism is reasonable, but only if Manchester City drop more points and Arsenal always win. But I even believe the opposite more, Manchester City will return to lead the Premier League standings by taking advantage of Arsenal's mistakes in the next few matches.
