LONDON - Christopher Samba joined Queens Park Rangers' relegation fight and Danny Graham left Swansea City for Sunderland as the January transfer window concluded amid a flurry of activity on Thursday.
QPR manager Harry Redknapp swooped for Congolese centre-back Samba in a club-record deal reportedly worth STG12.5 million ($A19 million), as he bids to haul the London club off the foot of the English Premier League.
QPR said the former Blackburn Rovers defender signed a four-and-a-half-year contract after arriving from Russian club Anzhi Makhachkala.
"I'm delighted to be back in the Premier League. It's the best league in the world to play football," Samba told the QPR website.
"I've been linked with the club for a long time. With Harry here though, he is really passionate and he wants to do something with the club."
Redknapp said: "Chris is just what we need. He's a monster. Great in the air, quick, a leader, strong, fantastic in both boxes, hard as nails. He's a proper centre-half."
QPR have also been linked with moves for Tottenham Hotspur midfielders David Bentley and Jermaine Jenas and Stoke City striker Peter Crouch, who has played under Redknapp at three previous clubs.
