There's no doubt that Tevez would be perfect for Juve. He would completely change the team & he fits Conte's needs perfectly. When he does try, he's extremely hard-working, presses like Vidal and always a threat on goal. I can't really see him coming here, though maybe, he wouldn't mind going to Italy. Italian is similar-ish to Spanish and the weather would be much better than Manchester.
He's exactly the world class player that we need that can win games by himself and to compete with the rest of Europe. If Juve signed Tevez, Rhodolfo and Ansaldi or Cissokho we'd definetly become the top club in Italy and would be just below the level of teams like Bayern, Chelsea and City. Definitely better than teams like Valencia, Tottenham, Liverpool, Atletico & Porto etc.
