Liverpool have confirmed that England defender Glen Johnson has signed a four-year deal at Anfield.
The former Portsmouth right-back moves to Merseyside as boss Rafa Benitez fine-tunes his squad for an assault on the Premier League title and plans for the UEFA Champions League.
Johnson was a target of ex-club Chelsea and Manchester City but has opted to move to Liverpool where he is expected to be a first-choice selection in the Reds' back four.
The fee is believed to be in the region of £17.5million, but there is some uncertainty regarding expenses still owed to Liverpool from Pompey following Peter Crouch's transfer to Fratton Park.
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."
Johnson's arrival casts Alvaro Arbeloa's future into doubt, with Real Madrid reported to be interested in the Spaniard.
