Fiorentina striker Christian Vieri admits he's unsure of what he'll do in retirement.

"I know that sooner or later I'll have to stop playing. I'll miss the locker room and training, matches, going around with the team because it's good times," said the 34 year-old.

"I have thought about coaching. First, a little yes, now I do not know, coaches are always stressed and exhausted."

Asked about working as a media pundit, Vieri added: "No, I could never write evil of my colleagues."
