Crystal Palace have announced the signing of central defender Jaroslaw Jach.
The 23-year-old has joined from Zaglebie Lubin for an undisclosed fee.
He has agreed a three-and-a-half year contract to become Palace's first Polish-born player.
"This is a dream come true," Jach told Palace's official website. "The Premier League was the league I have followed since I was little and I always wanted to come and play here.
"I am very pleased and I hope that I will be able to help Crystal Palace to stay in Premier League, and perhaps achieve bigger successes."
Jach is Palace's second signing of the January transfer window, following the midfielder Erdal Rakip earlier this week.
Palace's next Premier League match is at West Ham United on Tuesday, 30 January.
