He retired from global football with Spain past year after 102 appearances, a World Cup title and a European Championship crown.
Juve can still seal the title at home next weekend when they host Fiorentina, or even sooner if Napoli fail to beat Chievo on Sunday.
"It is very hard over the course of a season to always be at the highest level", said Valverde. They're far more pragmatic this season and the way I see the game pan out, is that they soak up pressure and try to catch them on the break with their pacy forwards should the situation arise.
