Juventus have activated the 40m euro purchase clause to sign winger Douglas Costa on a permanent deal from Bayern Munich.
The 27-year-old initially moved to Turin on loan for €6m last summer with a €40m option to buy.
And the Brazilian was one of the key players for Massimiliano Allegri as the club wrapped up a seventh straight Serie A title and fourth Italian Cup in a row.
“Juventus have exercised the option for the definitive acquisition of the registration rights of Douglas Costa from Bayern Munich for €40m to be paid in two financial years,” Juve said in a statement.
“Juventus and the player signed a contract of employment until 30 June 2022.”
