Liverpool have loaned out Juventus midfielder Arthur Melo until the end of the season.
The 26-year-old Brazil international made 31 appearances for Juventus last season but has not played this season.
“I’m really happy to be here and wearing this great jersey with this famous badge that represents so much in world football. It’s a dream,” said Arthur.
He comes to Anfield to ease Liverpool’s current midfield injury woes.
“I’m really happy and highly motivated to continue living my dream on the pitch and give it my all in a Liverpool shirt,” added Arthur.
Arthur, crowned 22 times by Brazil, won the 2019 Copa America alongside current Reds goalkeeper Alisson Becker and forward Roberto Firmino.
Like another compatriot Fabinho, he is seen as a player capable of filling a deeper midfield role that will not limit the path of youngsters Harvey Elliott, Fabio Carvalho and Curtis Jones.
The transfer window closes on Thursday 1 September at 23:00 BST.
Liverpool captain Jordan Henderson escaped with a torn hamstring in Wednesday’s 2-1 win against Newcastle United.
Reds boss Jurgen Klopp says the 32-year-old will “definitely not be available” for Saturday’s Merseyside derby against Everton.
Henderson joins Thiago Alcantara, Naby Keita and Alex Oxlade-Chamberlain on the Reds’ list of injured midfielders.
Arthur has his own injury woes, suffering from two separate ankle problems this year.
Deal makes “perfect sense” – analysis
Ian Kennedy, BBC Radio Merseyside
The idea that Liverpool would be interested in Arthur Melo seems to make perfect sense. First of all, he’s Brazilian – that always helps – and he fits in well with his compatriots who are already in the dressing room at Anfield.
But more importantly, he has experience at the highest level, is good on the ball, a good passer and seems capable of playing different roles in midfield. Hold, playmaker, box to box, all that.
A new midfielder may be needed given Jordan Henderson’s recent injury woes, although Jurgen Klopp says it has to be the RIGHT player.
Maybe Liverpool found him.
