Agent Mino Raiola can't say whether Zlatan Ibrahimovic will play beyond this season at AC Milan.
The veteran striker has a deal to June with Milan.
Raiola said: “We talk [about his future] every year.
"He is like a promissory note that expires every 12 months.
"I'm sure the day he doesn't feel like the orchestra's first violin, he will say 'I'm done' and will become a director."
