I know, and I know the ATP website keeps writing it's his last season, but in the French interviews, he never says that, really. And I rather trust what he says in French.
Just check his forum, he gave a long interview to l'Equipe in the middle of January, when the Deuce issue was already available:
Savez-vous si cette saison sera la der des ders ? – Rien n’est tranché.
Do you know if this season will be your last one? - Nothing is decided yet.
that sounds great
i read the australien open inteview after his game against federer, and there he said :
"i may be back"
