Liverpool have announced the signing of centre-back Sebastian Coates after the Uruguayan obtained a work permit.
The former Nacional 20-year-old is understood to have moved to Anfield in a £7million deal, having snubbed interest from Atletico Madrid.
Coates, who was the subject of a work permit hearing earlier on Tuesday, has passed a medical and will now join his international team-mates for Friday's friendly in the Ukraine.
A statement late on Tuesday night read: "Liverpool have confirmed the signing of Uruguay international Sebastian Coates on a long-term contract.
"The 20-year-old completed his transfer from Nacional after passing a medical and securing a work permit earlier today."
Coates was voted best young player during Uruguay's Copa America success this year and the presence of compatriot Luis Suarez at Liverpool influenced his decision to join the Reds.
The defender said on Twitter: "Very happy to sign for a big club and to be able to be a team-mate of a friend like Luis Suarez."
Coates arrives at Anfield with a promising reputation and is perceived as a long-term successor to Jamie Carragher.
Suarez himself said on Twitter earlier on Tuesday evening: "I want to welcome Coates, partner in the Uruguayan team, friend and great player who just signed for Liverpool!"
Charlie Adam, who this summer joined Liverpool from Blackpool, was also pleased to hear news of the transfer.
He said on Twitter: "Just read we have now signed Sebastian Coates welcome to LFC."
