The Italian midfielder had spent his entire career at Roma, having made 615 appearances for the club across all competitions – putting him second to Francesco Totti in the Giallorossi’s all-time appearance list – as well as winning the Coppa Italia twice and the Supercoppa.
The club confirmed in a statement that Roma’s final game of the season – at home to Parma – would be De Rossi’s last for the club he joined as a teenager in 2000.
Roma chief executive Guido Fienga said the club only informed De Rossi on Monday of their decision not to renew his contract.
“I apologised to Daniele, on behalf of the club, for not speaking to him sooner – it has been a problematic season,” Fienga told a news conference.
“The club is aware of the mistakes we’ve made, and we are reflecting on that. But we appreciate the way Daniele has accepted the decision.”
Fienga offered Rossi a director’s role at Roma but the former Italy international has decided to extend his playing career.
“I’m almost 36 and I know how football is, but I didn’t want to distract from our European (qualification) race,” De Rossi told reporters.
“I thank the directors for their offer – I respect it and appreciate it, but I still feel like a player.”
“Eventually, I would like to be a coach. At this point I don’t see myself becoming a director, but at Roma a role like that would have some meaning. I need to go away and study, to learn – it will be a long journey.”
