Liverpool have completed the signing of midfielder Charlie Adam from Blackpool.

The Scot, 25, signed a contract on Thursday after successfully completing a medical, the club's official website said. The length of the contract or the fee have not yet been disclosed.

"I am absolutely delighted to be here," Adam told Liverpoolfc.tv.

"It has been a long process but now I can't wait to get started and hopefully this will be a successful period in my career and in the club's history."

He added: "Liverpool is a massive club with terrific players and a terrific manager.

"I see this as the perfect development for me to come here, play with such wonderful players and hopefully help the team to win trophies, because that's the most important thing.

"I'm delighted to be able to walk out on the same pitch as some of the players here.

"There are good players at the club, top, top players who I want to learn from. I want to become a better player and hopefully bring something to the team.

"Hopefully we can have a successful period because it's been missing now for a couple of years.

"At the end of the day you get judged on trophies and as a footballer you want to win as many as you can.

"This club has had a lot of success over the years, so let's get back to doing that."

In the January transfer window the Reds had two bids - the second worth £6.5m - rejected by the Seasiders, who were reportedly holding out for £9m.

But Liverpool reopened talks at the end of the season for a player who had only 12 months left on his contract.

Adam, who was on the shortlist for the PFA Player of the Year award last season, joined Blackpool from Scottish Premier League club Rangers for £500,000 in 2009.

He was close to joining Tottenham before time ran out in the January transfer window earlier this year.

Adam becomes boss Kenny Dalglish's second signing since they finished sixth in the Premier League last season.

Another midfielder, Jordan Henderson, arrived from Sunderland in June for a reported £20m.

Roma's Brazilian goalkeeper Alexander Doni could complete a move to Liverpool in the next 24 hours, according to his agent Ovidio Colucci.

The clubs reached agreement over Doni's transfer last month but the keeper could not agree personal terms.

"We just have to ratify certain details with Roma," said Collucci. "If the deal is completed, Doni will join Liverpool on a free transfer and will sign a two-year contract."
