I think luck is still on Arsenal's side in the 9th week of the EPL. Arsenal were two goals behind after Cole Palmer opened the scoring for Chelsea with a penalty. Chelsea increased their lead to 2-0 at the start of the second half through a goal scored by Mudryk. Arsenal who were the favorites, were able to win because of their good performance since the start of the season, making a slow start at Stamford Bridge, Chelsea immediately took advantage of this situation to put pressure on Arsenal.
My words the other day really came true where when the match was difficult to predict once Arsenal's performance many believed that they would definitely win but of course Chelsea now (in the last 3 matches) is not Chelsea last season.
Now they seem to have a new motivation where their performance is different and that's a good thing.
Saying Arsenal were luckier I actually quite agree although not completely.
First David Raya's blunder which at that time if it can be maximized properly then I think Palmer has locked Chelsea's victory if it can be converted into a goal other than that for Rice's goal is also almost the same as Palmer's incident only the conditions are different and Rice can score goals and encouragement for Arsenal.
