have confirmed the signing of the 22-year-old midfielder Lucas Torreira from Sampdoria on a long-term contract .
He joins right-back Stefan Lichtsteiner, goalkeeper Bernd Leno and central defender Sokratis Papastathopoulos as arrivals at the Emirates this summer as new manager Unai Emery reshapes his first-team squad.
Torreira figures to replace Jack Wilshere who chose not to re-sign with his boyhood club after his contract expired, and instead joined West Ham on Monday.
"I feel calm," Torreira
"Now I am calm and I look forward to the future, which for sure will be very nice.
"I feel very happy. I want to make the most of this opportunity life has given me. I am really looking forward to starting this new adventure."
He has been handed the number 11 shirt for the 2018/19 campaign and will join up with the squad in early August.
“In Lucas Torreira, we have signed a young player who is a very bright talent in the game,” boss Emery added. “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.”
