Portsmouth defender Glen Johnson has agreed a four-year contract with Liverpool. The England right-back moves to Anfield in a reported £17million deal.
Johnson, 24, becomes manager Rafael Benitez's first signing of the summer.
Benitez told Liverpool's official website: "We were thinking about bringing in players with quality - that's the first thing.
"He is also English and that is important for the Champions League list. We were thinking about improving the team and Johnson is a very good player who will do that.
"He was important at Chelsea and in the last year at Portsmouth he has improved and is much better.
"One of the main things is his mentality - it's really good. He is a winner. I was impressed with the conversations I had with him. He wants to improve.
"We knew the market was going to be difficult this summer and some of it has been crazy. Manchester City and Chelsea were there - they were making offers.
"We had to be quick and the club acted quickly. It was down to the player whether he chose us or City or Chelsea and he chose us. It was very clear from talking to him that he wanted to play for Liverpool."
