Joe Cole has passed his medical and put pen to paper on a four-year contract at Liverpool.
The England international agreed to join the Reds on a free transfer from Chelsea earlier in the week and has now completed the formalities on his move to Merseyside.
The 28-year-old midfielder passed a medical at the club's pre-season training camp in Austria to bring to an end a lengthy transfer pursuit for new manager Roy Hodgson.
Cole's departure from Stamford Bridge at the end of the last campaign had sparked a transfer scramble among several Premier League clubs.
"Liverpool Football Club are delighted to announce that Joe Cole has put pen to paper on a four-year deal," confirmed a club statement.
"The England international has passed his medical and has been allocated the squad number ten."
Meanwhile, Hodgson has pledged to continue his prudent approach to rebuilding the Liverpool squad following his arrival from Fulham.
The cash-strapped Reds, who finished a disappointing seventh in the Premier League last season, are currently seeking new owners.
"We don't have the unlimited funds that teams like Manchester City and even Tottenham to some extent these days, seem to have," Hodgson told the club's official website.
"In this current situation we don't have that. On the other hand some money is being made available and we are doing everything to use that money as sensibly and as intelligently as we can.
"We had quite a good squad of players last season. We've talked about (Steven) Gerrard, (Fernando) Torres, (Pepe) Reina - these players means there is a certain strength to the team whatever we do.
"We would like to make some changes. Every manager who comes to a new club would like to make changes, to bring in some fresh players."
One of those changes will be the departure of defender Philipp Degen, who has been told he is free to find another club after two injury-plagued seasons at Anfield.
