Brazilian defender Alex was well loved by Chelsea fans during his time at Chelsea due to his rugged style of defending and his fierce free kick.
Alex has announced his retirement from football and he admits injury forced him to hang up his boots.
“I made the decision, with my family, to leave football,” Alex said as quoted by Tribal Football.
“To get back on the field, I would have to have surgery and complete nine months of rehabilitation.
“For that pain, I could not bear it.”
34-year-old Alex last played for Italian club AC Milan.
