Leicester City boss Craig Shakespeare has confirmed Marcin Wasilewski is leaving.
The defender will be off contract next month.
“Marcin's been an absolute pleasure to work with over the last four years," Shakespeare said.
“The influence he has had and the contribution he has made goes beyond what people see on the pitch. He's one of the best professionals I've ever worked with.
“I remember when we signed Marcin – we knew we were getting a very experienced, international footballer with a lot of quality.
“But we also got an outstanding character, a leader and someone who would make everyone around him better with his relentlessly high standards every day.
“He's been a terrific servant to the Club, deserves enormous thanks and our very best wishes for whatever comes next in his career."
