Arsenal manager Mikel Arteta said his side were "10 times better than last season" despite dropping points for the first time in this Premier League campaign against 10-man Fulham.
The Gunners thought goals from Bukayo Saka and Eddie Nketiah would be enough for victory after falling behind in the first minute at Emirates Stadium.
But, after Calvin Bassey was sent off, Joao Palhinha rescued a 2-2 draw for Fulham by scoring from close range in the 87th minute.
"We go 2-1 up and you have to defend for your life, you cannot concede the goal after everything we have done," said Arteta.
