Chelsea should focus on improving their scoring performance in the Arsenal match. Because it seems like productivity is their main problem at the moment. For three weeks, the number of most goals scored in a match has been only one. Actually they showed big weaknesses in defense against Brighton also but it wasn't a general problem if we take a bigger time period into account.
Honestly speaking , Chelsea really need to work on improving their performance if they want to win this game, Just seem like Didier Drogba position is unreasonable since his departure, Chelsea hasn't gotten an incredible goal scoring striker like him , and rarely you find Chelsea players making it to the highest goal scorers in the premier league. Aubameyang needs to wake up in this game and do the needful because this was his former club. Arsenal loves scoring goals and could teach Chelsea how to do that , if Chelsea be on laxity.
Chelsea have been unstable in the past three weeks, their goal scoring margin has also dropped and it seems their attacking options are not so effective now. Against Arsenal on sunday they will need to play a lot better to hold off Arsenal from taking advantage of their mistakes and weak spots because the way at which Arsenal are performing I see them in better position to win the game.
