Liverpool have signed Spain winger Albert Riera from Espanyol for an undisclosed fee.

The 26-year-old has signed a four-year contract at Anfield after choosing Rafael Benitez's side over a host of other clubs including neighbours Everton.

Riera, who has been given the number 11 shirt at Anfield, has previously played in the Premier League in the 2005-06 season when he was on loan at Manchester City.

"Riera has the qualities we were looking for," said Benitez.

"He's a left-footer who normally plays on the left wing, he's good in the air, strong, powerful and a good crosser of the ball."

Riera became Liverpool boss Rafael Benitez's number one transfer target after England midfielder Gareth Barry committed his future to Aston Villa.

Benitez has been short of options down the left-hand side with Ryan Babel away representing Holland at the Olympics, while Steven Gerrard has looked ineffective out of position on the wing.

Landing Riera has left Benitez, therefore, understandably delighted.

"He's the kind of player we have been talking about. He can beat players and get good deliveries into the area for our strikers.

"We've known about him for a long time, since he was at Mallorca and then through his career with Bordeaux, Manchester City and Espanyol.

"He can speak English and of course he knows the Premier League, which is a big bonus. Usually foreign players need time when they go to a new country, but Riera already knows the league and the style of football.

"He also had offers from other English clubs but he said no to them because he wanted to come and play for us. That means a lot to me because it shows the commitment he has to play for Liverpool."
