World Cup winner Daniele De Rossi will retire from football at the age of 36, sources have told ESPN.

De Rossi, who spent 18 years with boyhood club Roma after making his debut in 2001, left for Boca Juniors in July 2019 and helped the Argentine club reach the Copa Libertadores semifinals.

Despite having signed a one-year contract, after returning to Argentina following a Christmas break in Rome, sources told ESPN the midfielder reported back for his medicals but left the training ground and decided he would hang up his boots.

De Rossi, 36, was part of Italy's 2006 World Cup-winning squad, coming on as a substitute in the final victory over France. He had been sent off for a vicious elbow in the second match of the tournament and received a four-match ban, only returning for the final.

His 616 appearances for Roma is second only to Francesco Totti's 786 in terms of the most games played for the Giallorossi.

He was given his professional debut by Fabio Capello in 2001 -- just six months after they clinched their last-ever Serie A title -- in a Champions League clash with Anderlecht.

De Rossi never won Serie A, but finished as a runner-up on eight occasions. He also helped Roma win back-to-back Coppa Italia trophies in 2007 and 2008.
