Pierre-Emerick Aubameyang says Alexandre Lacazette's absence has impacted Arsenal.
The Gunners blew a two-goal lead to draw 2-2 with Watford at Vicarage Road on Sunday.
"I don't want to accuse anyone, you could say that us the attackers could have killed the game off and score a third goal, so I am not going to say it is someone's fault," he said.
"It is a shame to concede goals like we did I think it [Alexandre Lacazette's absence through injury] affects us.
"We know very well that he brings us so much in these sorts of games."
