ARSENAL have completed the £22million signing of midfielder Lucas Torreira from Sampdoria.
The Uruguayan becomes Unai Emery's fourth signing of the summer as he continues a squad overhaul.
Torreira underwent a medical at Arsenal's London Colney training complex on Monday after agreeing personal terms.
Arsenal had agreed a fee with the Italian side at the World Cup but the deal was put on hold while the 22-year-old participated at the World Cup.
Uruguay were knocked out in the quarter-finals and he wasted no time jetting to the capital to finalise the deal.
Emery told Arsenal's official website: "In Lucas Torreira, we have signed a young player who is a very bright talent in the game.
"A midfielder with great quality, I have enjoyed watching his performances for Sampdoria in the past two seasons, and we all saw him do very well for Uruguay in the World Cup.
"He is a young player already with good experience, but who wants to keep on growing. We welcome Lucas to Arsenal and look forward to him joining us soon for pre-season.”
Sampdoria confirmed the deal on Twitter by writing: "Torreira signs for Arsenal. Thanks and goodbye from the President and Sampdoria."
Meanwhile Arsenal are closing in a deal to land youngster Matteo Guendouz.
The 19-year-old midfielder and French U-20 international will pen a five-year contract at the Emirates.
Goalkeeper Bernd Leno, right-back Stephan Lichtsteiner and centre-back Sokratis Papastathopoulos have already signed up for Emery’s revolution.
