PsG is possible, depending on who the next coach there is. I think he's already linked with Monaco but he has turned that move down coz he's more interested in Juve's offer if rumors are to be believed. Also let's not forget, Mancini is being considered by both those teams.
Argentina is also realistic, but when you see that he's only 29 years, that kind of move can wait, especially considering he will still get to play in the CL and the world cup is coming up next year. Tevez is too big a player to shorten his career prospects just yet. Maybe in 2-3 years, Argentina can see out his playing days or lack of ambition, but for now, a challenge like Juve would be very tempting. Let's see. Although if we could snap him up, I think the team would be suitably reinforced not just for Serie a, but more importantly, Europe too.
