Jose Enrique insists his transfer from Newcastle United to Liverpool is motivated by a desire to win trophies, not money.
Enrique, 25, sealed his £6 million move to Anfield on Friday after completing a medical at Liverpool's Melwood training ground on Thursday.
"This is one of the happiest days of my life,'' he told Liverpool's official website. "I have come to one of the biggest clubs not just in England, but in the world. I am really, really happy.''
He had previously been quoted as saying he wants to join a club playing Champions League football, but he clarified that it is success that he craves, not deep pockets.
"My move is purely dependent on the sporting opportunity, not money," he said in The Sun. "I want to fight for titles and I think it more possible to do that with Liverpool than Newcastle."
Enrique was fined two weeks' wages in January for criticising Newcastle's transfer policy on Twitter following Andy Carroll's £35 million departure, and the Spaniard has now followed the striker to Anfield.
"I prefer not to comment further on that," he said on the disciplinary procedure. "But Newcastle did promise to solve my situation before the season and this has happened."
If all the paperwork on the transfer is cleared by the Premier League by noon then the player would technically be available for tomorrow's opening league match at home to Sunderland, although whether manager Kenny Dalglish would throw him in after just one training session remains to be seen.
"They have won a lot of things including the Champions League,'' he said. "They have amazing players and I hope to win things here. In Spain there is a saying 'When the train comes in, you have to take it.
"This is the first time a big club has come in for me and I had to take it (the opportunity). I am really happy. Everybody speaks about the fans here and they are amazing. I am looking forward to it. I am looking forward to playing in front of the Kop. I hope it will be this weekend, but if not I can wait.
"If the manager needs me, I am ready to play. I have already played for Newcastle in pre-season, not every game but two or three games and I am fit and if the manager needs me, I am ready to play.
"My ambition is to win everything with Liverpool. This year we won't play in the Champions League, so the most important thing is to try to win the league.''
The Spaniard will link up at Anfield with former Newcastle team-mate Carroll, who moved in January, and the defender said he and Dalglish's other signings were a significant factor in deciding to follow the same path.
"I am excited - it shows Liverpool's ambition,'' Enrique said. "They spent a lot of money in January on Andy and Luis Suarez and this summer they've spent a lot of money on other players.
"You can see they have big ambitions and that's why I came here - because I want to win things and I think I can do that here.''
Director of football Damien Comolli believes Enrique will be Liverpool's final signing before the end of the transfer window.
"You can never say never, but it is likely,'' he said. "I am convinced we were right in what we wanted to do. We've strengthened all the areas we wanted to strengthen with quality.
"I think there is a lot of debate about transfer fees paid - not just with Liverpool but throughout the Premier League. But if we have signed a player it is because we were happy to pay the price. For us it is not even a debate.
"We are very happy to have done the business we have done, we think it makes a lot of sense from a footballing point of view and makes a lot of sense from a financial point of view.''
On Enrique's qualities Comolli added: "I am very pleased to have signed arguably one of the best left-backs in the Premier League. He is a very quick, strong and powerful athlete with good technique.
"He knows the league and what to expect and what to expect when you play for Liverpool; we know he is going to come in and hit the ground running. We think if he does well here, he could be a candidate for the Spanish national team.''
Midfielder Alberto Aquilani, who has been linked with a move numerous times, has been given the squad number 15 but left-back Emiliano Insua's future appears to have been decided by Enrique's arrival as he has not been given one.
