Hangeland feels Rene Meulensteen's men can pull clear of trouble despite their lowly position just a point outside the relegation zone.
"It is real battle, but we are prepared to get enough points to stay in the league," the Norway centre-half said.
"We are playing a slightly different way now, we are very organised and all know what we are trying to do.
"It is about getting that transformed into results on the pitch, and I am confident that will happen."
