Milan Baros was part of the squad who won the Champions League for Liverpool in 2005 and it was approximately a year after he won the Euro 2004 golden boot where his country reached the semi finals.
The 38-year-old Czech superstar currently plays for Banik Ostrava in his home country and has struggled with Achilles and calf injuries in recent years.
“The head would like to, but the body has already said stop,” said Baros.
“Those health problems have been with me for a long time and the body is not working as I was used to in my career.”
He added: “The reasons are clear. Age cannot be stopped. Secondly, my health side, which has been bad for the last season. After any workload, I started to feel such pain that it is not possible to continue my professional career.”
After leaving Liverpool he featured for other club like Aston Villa, Portsmouth where he won the 2008 FA Cup, Galatasaray, Lyon, and Antalyaspor before returning to Czech Republic in 2014 and he retired from international football in 2012.
