Arsenal defender Johan Djourou concedes they were "embarrassed" at AC Milan this week.
While the Swiss defender was hurt by the nature of the loss, he insists it is imperative to make amends at the Stadium of Light.
"We must show a different attitude. It is a big game because it is the FA Cup and we want to go far in that competition," Djourou told Arsenal Player.
"We have to be in a different mindset and I hope we will be because as human beings you do not like to be embarrassed and not respond in the next game."
