The former Juventus star is unsure where his future lies beyond the end of his two-year deal, with possible moves back to Italy - and a return to Turin in particular - having been mooted.
"I don't know what I'll do next season," said the Italy legend.
"I'll evaluate at the end of the season. My hearts says for me to play, but I must also listen to the legs.
"This will be the big question of my summer. I have a meeting with the club president at the end of the season. Their one will be the first offer I listen to."
