Pierre-Emerick Aubameyang and Alexandre Lacazette were both on target at the weekend but our strike duo are likely to both drop out against Brentford which will open the door for Danny Welbeck to start in attack.
Arsenal nearly scored from their first chance 10 minutes later when Pierre-Emerick Aubameyang's cutback from the left found Nacho Monreal, who forced Jordan Pickford into a sharp save from seven yards out.
"A big thanks to Petr Cech because he took a lot of balls today and we won our first clean sheet", the former Lyon forward responded.
The Bees travel to the Emirates Stadium looking to cause a third-round upset and Emery is expected to make wholesale changes to his team, with Holding looking to make his second start of the campaign.
Arsenal goalkeeper Petr Cech on Monday asserted that his side lacked winning mentality under the previous manager Arsene Wenger and often succumbed to the pressure posed by resolute opponents.
Theo Walcott scored 56 times at the Emirates during his 12 years with Arsenal and the Everton winger, making his second return to his old club, nearly added to that total just before half-time. The French striker took one touch from Ramsey's pass and curled a shot in off the right post from 16 yards out on the left.
The Gunners took the lead against the run of play, with the France global having a poor game and the knowledgeable commentators had suggested that he was going to be replaced by Iwobi, only for Emery to change his mind.
"Like on Sunday, for example, after Sokratis' injury it was important how Rob played and helped the team to find the performance to win against Everton".
"There was a big mistake by the assistant because their second goal is clearly offside and that was a big crush for us", Silva said. "I think we're growing, improving every day".
"We had three or four clear chances".
Richarlison was lively in his return from a red card suspension, forcing Cech into a two-palmed save in the 21st minute.
For Milner, he has played in seven matches (six Premier League and one Champions League), also scoring two goals - one against Paris Saint-Germain in Europe - while assisting twice for his Liverpool teammates.
