Just today, after selling Heung-min Son to "Tottenham", Leverkusen's "Bayer" announced the acquisition of Slovenia national team and Dortmund's "Borussia" defender Kevin Kampl.
The 24-year-old player spent most of his career at "Bayer" - from 1997, when he joined the team at just 7 years old, until 2011.
He only spent half a year in Dortmund, previously representing Salzburg's "Red Bull", "Aalen", "Greuther Furth" and "VfL Osnabruck" teams.
