Former Spain international midfielder Iker Muniain raised the prospect of retirement on Friday after parting ways with Argentine club San Lorenzo.

The 32-year-old had been tied to the Buenos Aires club until December but exercised an option to terminate the contract early, citing personal reasons.

"I'm here to announce that I'm leaving San Lorenzo but a little piece of me will stay here forever," Muniain told a news conference in Buenos Aires, adding that he would need time to think about his future.

"This is the first time I've considered quitting playing. There is a good chance that this will happen, and I'll be giving it some more thought."

Muniain made 26 appearances across all competitions for San Lorenzo, scoring four goals and providing one assist, after joining the club on a free transfer from Athletic Bilbao last September.

His time in Argentina coincided with an institutional crisis at San Lorenzo, including a corruption scandal engulfing the club's president, Marcelo Moretti, and financial troubles that delayed player salary payments.

Muniain did not indicate whether the off-field turmoil influenced his decision but insisted he would recall his time at the club fondly.

"I've been able to experience nine or 10 truly wonderful months despite all the circumstances and problems that have arisen at times," said Muniain, who has two Spain caps. "It's been very special, it's been very beautiful. It has been worthwhile and the memories will last a lifetime."
