Charlton have signed Sunderland defender Greg Halford on loan until the end of the season, the Barclays Premier League club have announced.

The 23-year-old defender moves to The Valley after making eight league appearances for the Black Cats following his switch to Wearside from Reading last summer.

Pardew told his club's website: "Part of doing business is to make sure you try to do something that's useful for your club.

"I lost Jermain Defoe in a similar situation when I was at West Ham United, and brought in Bobby Zamora.

"Hopefully, we can have similar success with Greg. He's coming here on loan and I think he's got a lot to prove.

"It didn't work out for him at Reading, it didn't work out for him at Sunderland, so I think he needs to be a success here, but I think he will be a massive asset for us."
