Portsmouth have completed the signing of Charlton defender Djimi Traore.
The left-back moves to Fratton Park on a two-and-a-half year contract for a deal reported to be worth £1million to The Addicks.
Traore becomes manager Harry Redknapp's second signing of the January transfer window.
The 26-year-old, who only joined Charlton from Liverpool last summer, is joined on the South Coast by France Under 21 midfielder Arnold Mvuemba.
Mvuemba joined Pompey in a loan deal until the end of the season earlier this week.
Traore's place at Charlton seems certain to be taken by Manchester City's Ben Thatcher, who is on the verge of completing a move south.
