Eintracht Frankfurt have exercised the option to purchase Filip Kostic on a permanent basis from HSV.
The Serbian international has put pen to paper on a four-year deal at the Commerzbank-Arena, keeping him at the Eagles until 30 June 2023.
Kostic had previously been on loan at Eintracht from the 2. Bundesliga club.
The left winger is HSV’s all-time record transfer signing and is having a good season in Frankfurt.
Eintracht Frankfurt board member Fredi Bobic was pleased with the deal, telling the club’s official website:
“Filip has been a really lucky find for us. He is energetic, focused and adaptable, and that has helped him make a real contribution to the success we’ve had this season.”
Filip Kostic has scored six goals and made 11 assists from out wide in his 33 Bundesliga appearances. He has added a further four goals and two assists in 12 UEFA Europa League games.
The midfielder came through the youth ranks in his homeland with Radnicki Kragujevac making his debut as a 17-year-old in 2010 before moving to the Dutch Eredivisie with FC Groningen two years later.
After impressing in the Netherlands, Kostic was signed by Fredi Bobic’s VfB Stuttgart in 2016 before he became HSV’s record signing two years later. Having been relegated from the Bundesliga in his second season at the club, the Old Dinosaur decided to loan the winger back to the top flight and to Eintracht Frankfurt, with an option to purchase during his time at the club.
