Ones to watch
Although he did not start the match against Brentford due to a lack of match fitness Bukayo Saka was exactly the player Arsenal looked like they needed. His pace and Directness in taking on defenders helps Arsenal create chances.
Arteta could bring him into the side to replace Gabriell Martinelli on the left hand side , who had a very quiet game against Brentford.
Anyone who watched England at the Euros knows the vital role Saka played them in unlocking defenses, and against a team with a rigid defence such as Chelsea he could be the key to unlocking it and help Arsenal to win the game.
By far one of the biggest transfers of the summer, Romelu Lukaku will be hoping to make an instant impact if he starts against Palace. Having scored 47 goals in 72 matches in Serie A as well as four goals at the euros this summer.
Chelsea will be hoping he will be able to replicate his from for them this season. If Lukaku does start it means the Arsenal defence will have to be absolutely perfect and not make any mistakes otherwise they will be punished.
In particular Ben White who had an absolute nightmare against Ivan Toney's physicality last week, losing most of the ariel duels to him.
