Hertha Berlin have completed a move for Basel midfielder Valentin Stocker.
The 25-year-old Swiss international has penned a four-year deal with the Bundesliga side for a fee understood to be in the region of £4m.
"Valentin Stocker is an exceptional player who fits perfectly the profile of player we were looking for," Berlin's general manager Michael Preetz is quoted as saying by BT Sport.
"He is going to give our attacking play a lot of variety and an additional goalscoring threat next season."
Stocker leaves Basel following a nine-year association with the Swiss club.
