Hangeland said: "I have to say, what's going on?"
Dutchman De Boer was sacked after last Sunday's (Sept 10) 1-0 loss away to Burnley meant Palace were the first team in England's top flight to lose their opening four games without scoring a goal since Preston North End 93 years ago.
"It is very rewarding to find myself here now, in hard times of course, as the Palace manager at a club that I have always loved and admired with a huge potential".
Hodgson took training at the club's Beckenham HQ for the first time yesterday after taking over as the new manager on Tuesday.
'I'm certain we will pull away from the mire and I'm very confident the players we have here will help us achieve our goal, which is to make certain we don't get relegated'.
Palace represent Hodgson's fifth Premier League appointment of his managerial career, after Blackburn, Fulham, Liverpool and West Brom.
"We're four games in and the start has been a poor one, we can't deny that, but there's 38 games in the league season and there's 34 more to play and quite frankly the relegation issues are not going to be decided this side of Christmas, they're probably not going to be decided this side of Easter".
With manager Arsene Wenger expected to ring the changes before the vital clash with last year's Premier League champions Chelsea at Stamford Bridge, the likes of Wilshere could get valuable game time to impress the Arsenal boss and potential suitors.
He added: "I am very excited to be back in club football and it is a long while since I have enjoyed the day to day sessions of training".
Ray Lewington, Hodgson's deputy with England, will also be his assistant at Selhurst Park having had two spells as the club's caretaker manager.
