Borussia Dortmund have confirmed the signing Kevin Kampl from Red Bull Salzburg for a fee believed to be in the region of €10 million.
The 24-year-old midfielder was born in Germany but represents Slovenia at national team level and started his career at Bayer Leverkusen.
Kampl has been a key player for the Austrian giants since his move from Aalen in 2012, helping them to the round of 16 in the Europa League last season and the domestic league and cup double.
The midfielder completes the move as the German giants look to boost their ranks and climb back up the table, as they lie in the relegation spots in the Bundesliga after a horrendous start to their domestic campaign.
"Kevin Kampl will sign a long-term contract with Borussia Dortmund, keeping him at the club until 2019. Both clubs agreed details of the transfer fee shall remain undisclosed," a statement on Dortmund's official website read.
"Kevin Kampl is a versatile attacking-midfielder who we have been observing for some time. His style of play fits in perfectly with our own,” BVB's sporting director, Michael Zorc, added.
Red Bull sporting director Ralf Rangnick said: "The transfer to the Bundesliga is the next logical career step for Kampl. So he's moving to a club who have performed very well both in Germany and in Europe on a regular basis over the last few years.
"He's an exceptional player with a lot of versatility, who has developed brilliantly in the last two and a half years. We wish him the best and all the success in his new challenge."
