On Tuesday, VfB Stuttgart announced the arrival of Lech Poznan's Marcin Kaminski.
The defender joined the Swabian outfit on a free transfer, and has signed a three-year deal to take him through to 2019.
He joins Jean Zimmer as their second summer arrival, while Marco Rojas will also stay with the club after returning from his loan spell at FC Thun.
Plenty of experience at a young age
Kaminski began his career at Lech and has remained there ever since, gaining experience at domestic and European levels.
Despite being just 24, the centre-back has racked up over 200 appearances for one of Poland's biggest clubs; including 19 in the UEFA Europa League.
The move to Germany could act as a catalyst to revive his national career, having been a member of the Euro 2012 squad. He has just four caps to his name, however.
Luhukay and Kaminski have their say
"We are delighted about the signing of Marci," Jos Luhukay said. "He possesses masses of potential and wants to take the next step in his career with Stuttgart."
The new Stuttgart boss added, "He is motivated to help us and we firmly believe he will quickly come to terms in Germany."
Kaminski also gave his views on the move, "VfB is my first station abroad. I want to take my next step here in Stuttgart, at a club with a long history."
He continued, "My goal in Germany, with its strong leagues, is to become a better player. VfB belong in the Bundesliga."
The centre-half concluded by reassuring fans he is up to the task: "We will be under pressure to win immediate promotion, but it’s a challenge which really appeals to me."
