I read that Buffon is renewing one more year until 2016 and that when he retires will be offered coaching. Other contracts ending in 2016 are the ones of Evra, Pirlo, Tevez and Allegri, I don't think Barzagli will be a starter in 2 years. Definitely 2016 will be the critical season to define how the new Juve will play (formation, tactics, players).
