The Eagles confirmed the signing on their official Twitter feed:
Hangeland was a stalwart defender for Fulham after joining the side during the 2007-08 winter window. He spent the next six-and-a-half seasons with the Cottagers, appearing in more than 150 matches across all competitions.
A frustrating campaign caused Fulham to get relegated after last season. With that comes changes to the squad, and the veteran defender was part of that overhaul.
Now, the centre-back joins a Palace side that finished in the middle of the pack last season. The club would love to take another step forward despite what amounts to an unheralded squad.
It's a hard-working group, though. Squawka Football passed along comments from Hangeland after the move was announced, and it sounds like he's going to fit right in:
At the very least, the signing gives manager Tony Pulis some options at the back. Hangeland could step into a full-time role or simply be part of a rotation playing alongside Scott Dann in the centre of defense. A clearer picture should emerge once he gets more involved at training.
Either way, Ed Malyon of the Daily Mirror believes it's a good fit:
Hangeland probably won't display the form he did during his peak seasons with Fulham. That said, at 33, he should still have some solid football ahead of him, and the fact Palace were able to secure him on a free transfer limits the risk.
Furthermore, it's an addition that makes it clear the Eagles will be a very tough side to play against once again. The veteran adds to the team's size and depth on defense after finishing seventh in goals allowed last season.
