Defender Paul Konchesky has been reunited with former manager Roy Hodgson after finally completing his move to Liverpool from Fulham.
The 29-year-old has signed a four-year contract, with Reds reserve team players Lauri Dalla Valle and Alex Kacaniklic moving in the opposite direction as part of the deal.
Konchesky was at Anfield to watch his new team's victory over West Brom on Sunday but the completion of his deal was held up by negotiations and medicals for Dalla Valle and Kacaniklic.
The two-cap former England international, who played under Hodgson at Fulham, will provide much-needed competition for Fabio Aurelio at left-back.
Argentinian Emiliano Insua is destined to leave the club, with a proposed loan to Galatasaray, after an earlier move to Fiorentina collapsed over personal terms despite the clubs agreeing a fee.
In the wake of Dalla Valle and Kacaniklic's departure Liverpool have moved to strengthen the reserves with the signing of 16-year-old Suso from FC Cadiz on a scholarship agreement and MTK Budapest's Hungary Under-17 international Adam Hajdu on a temporary transfer until next June, with both deals subject to international clearance.
Suso, a 16-year-old forward, impressed for the reserves in pre-season and even featured as a late substitute for the first team in the friendly defeat to Borussia Moenchengladbach.
