Ottmar Hitzfeld's side are aiming to bounce back following the 1-0 defeat by Chile in Group H.
Von Bergen said: "We are angry at the moment but we are still in with a great chance, provided we beat Honduras.
"We were completely thrown by the red card against Chile. We let ourselves be pressed too far back at the start, although we went out there intending to attack. It is hard work with 10 men."
