Spain winger Riera was unveiled at the Reds' Melwood training ground on Thursday and immediately set his sights on adding another chapter to the Merseyside club's rich history.

"At Liverpool the most important thing is when you are on the pitch to think only about winning," Riera said.

"It is important to fight for everything - to fight to win the Premier League, the Champions League and the two cups. I am sure we will enjoy fighting for all of these titles.

"We want to challenge for everything until the last minute of the last game.

"I want to be in finals and to challenge for the Premier League as well because for this club it is very important to challenge for the league."

Riera's only previous experience of English football came with Manchester City during a largely unremarkable six-month loan spell, but the player is convinced he is now better equipped to make an impact.

"It was different when I was at Manchester City - I came in January for the second part of the season and we were playing for mid-table," he added.

"Also I was 22 and now I have three years more experience, which is very important in football.

"I have played in a UEFA Cup final and I have played international football so now I am prepared to be at a big club like this."
