Kazuyoshi Miura said Wednesday he remains undecided about a potential move to Oliveirense in the Portuguese second division.
Japanese football's oldest active player at 55, Miura has received an offer that, if he accepts, would see him playing in his fifth country abroad after Brazil, Italy, Croatia and Australia in a 38th pro season.
"Honestly speaking, I still have worries about my fitness," Miura, who scored two goals in 18 games for Suzuka Point Getters in the fourth-tier Japan Football League this year, said after training in Osaka.
"I hope to assure myself I have the body and spirit that will dispel that (concern) and allow me to compete over there."
Miura visited Oliveirense earlier this month and was to reply to their offer by Christmas.
"Frankly, it's still difficult to give them an answer. I can't go just to be put on something of a limited rehab training menu," Miura said.
He also added there has been no talk yet of extending his stay at Suzuka, where he has been on loan from Yokohama FC, who will return to the J-League first division next year.
