Liverpool have completed the signing of central defender Steven Caulker on loan from QPR until the end of the season.
Caulker spent the first half of this term with Southampton but was restricted to one Premier League start under Ronald Koeman and last featured during December s 6-1 defeat to Liverpool in the quarter-finals of the League Cup.
The 24-year-old, who scored on his solitary appearance for England against Sweden in November 2012, is eligible for selection when Liverpool host Arsenal at Anfield on Wednesday.
