Despite the uncertainty surrounding the future of the team, Hangeland wants the players to remain focused ahead of their fixtures against Stoke City and Crystal Palace.
"The next two weeks that will decide whether we're in the Premier League or not. There's no time for feeling sorry for ourselves," the Norwegian told the Daily Star.
"We've made a lot of mistakes this season and now is the time to really show what we're made of and go and win the next two weeks.
"We have 31 points and we need six points from the next two to stay up, probably, and that has to be our target."
Fulham's penultimate game of the season is on Saturday when they travel to Stoke.
