Liverpool have signed Japan midfielder Wataru Endo on a four-year deal, subject to international clearance and work permit application.
Endo, 30, has signed for a reported £19million (€22.2) fee from Bundesliga club Stuttgart.
He told Liverpoolfc.com: "I'm very happy right now and I'm so excited to join a big club in Liverpool.
"It feels amazing and this is my dream. It's always (been) a dream to play (in the) Premier League and with one of the biggest clubs in the world. It's a dream come true for me."
"First of all, I'm really happy that we can have an agreement with a club and a player which is really cool," said manager Jurgen Klopp said.
"I am from Germany, I watch a lot of Bundesliga, I've known him since he is at Stuttgart, I liked him pretty much from the start when he started playing there.
"He's a little bit of a late bloomer and usually for us for the way our owners see it, he was already too old when he joined Stuttgart but I obviously have a different view on that and I always liked him.
"The last week was obviously a tricky one, no doubt about that. But when you have a problem you can stick to the problem or find a solution, I'm more than happy to have the solution."
As for losing out on Caicedo and Lavia, Klopp added: "There's absolutely nothing to say about that. The transfer business is like that - you talk to people, the players and clubs and sometimes it works out and sometimes not.
"There's nothing else to say about that. All things that were said in these conversations, they stay between me and the specific other party, nothing to say about that, really."
Endo's arrival comes after Liverpool were unsuccessful in trying to sign Moises Caiceido and Romeo Lavia, both of whom have joined Chelsea.
Earlier today the Blues completed the signing of midfielder Lavia from Southampton for a reported £53million, rising to £58m, taking their total number of first-team acquisitions this summer to eight.
The 19-year-old, who has played just 29 times in the Premier League, has signed a seven-year deal having made clear earlier this week his desire to move to Stamford Bridge over Liverpool, who also had a bid accepted.
The club has now spent more than £350m during this transfer window once performance-related add-ons are taken into account, though that has been significantly offset by fees received for player sales.

Lavia told the club's website: "I can't wait to meet all my new team-mates and build a chemistry together to achieve great things together."
Lavia, who made his Belgium debut in a friendly win against Germany in March, will likely compete with Enzo Fernandez and fellow new-signing Moises Caicedo - the two most expensive players in English transfer history - for a starting place in Mauricio Pochettino's midfield.
Chelsea broke that record for the second time in eight months on Monday with the capture of Caicedo from Brighton for an initial £100m, possibly rising to £115, eclipsing the £106m they paid Benfica for Fernandez in January.
Co-sporting directors Laurence Stewart and Paul Winstanley said: "We are very pleased to welcome Romeo to Chelsea.
"He demonstrated his quality in the Premier League last season at Southampton, showing maturity despite his young age, and is a player we have monitored for some time."

Manchester United remain in talks to sign defender Jonny Evans on a permanent basis despite the collapse of Harry Maguire's proposed move to West Ham.
Evans, 35, joined on a short-term deal to cover United's pre-season fixtures in July, but that contract has now expired.
Erik ten Hag has revealed talks are ongoing with the United academy product, who watched Monday's 1-0 win over Wolves from the director's box at Old Trafford.
"In this moment, he is not (under contract) but we are talking," Ten Hag said. "We will see. We are in talks and when we have news we will bring it."
United's pursuit of the Northern Ireland international, who left Old Trafford for West Brom in 2015 and became a free agent this summer when his contract with relegated Leicester expired, has continued even though Maguire now appears set to stay at the club.
United accepted a £30million offer from West Ham for their former captain last week, but that move stalled with Maguire wanting to stay and fight for his place.
Ten Hag offered the 30-year-old some encouragement when asked what he needed to do to get back into the side.
"I am happy he is here, we need a good squad," the Dutchman said.
"We have four good centre halves and including Luke Shaw we have five, and we need it because we are going to play 50-60 games this season. All the players are internationals so we have a lot of load to cover.
"I am happy Harry Maguire is here. He is going to have to fight for his position as does everyone in the squad.

Newcastle have reached agreement with Chelsea over a deal for teenage defender Lewis Hall.
It is understood that talks over the 18-year-old's move to Tyneside have reached a successful conclusion and that he will become the club's fourth major summer signing.
Magpies head coach Eddie Howe confirmed his interest in Hall at his pre-match press conference on Friday morning, and indicated that the move - initially at least - would be on a loan basis.
Asked about the player, Howe said: "Let's wait and see what happens today. He's a player that I like, very versatile, really good potential."
Asked further if the move would be on a loan basis after admitting last week that the club would have to be "creative" in following up summer swoops for Sandro Tonali, Harvey Barnes and Tino Livramento, Howe added: "Yes, I think it is, yes."
Howe also confirmed that completion of the deal would effectively bring an end to the club's incoming transfer business.
He said: "I think if we were able to bring a player in, that would be our transfer business concluded unless there were injuries within our own players."

Brazil international Geyse Da Silva Ferreira has made a permanent move to Manchester United, the Women's Super League club have announced.
The 25-year-old forward joins United after winning the Spanish league title, Spanish Super Cup and Women's Champions League at Barcelona last season.
"I am very happy to be here," Geyse told manutd.com. "Signing for United has been a very special day for me and my family.
"I am very grateful for this opportunity and thank everyone for making it happen."
United have not disclosed the length of the player's contract
