He is expected to be included in the Italy squad for the Euro 2016 qualifiers in Poland and Slovakia.
Javier Martinez was signed on loan from Manchester United, having played under Louis van Gaal in the United States.
The 24-year old is expected back in Italy next week.
Antonio Conte will be hoping for more from his first squad in six months, as his squad is struggling to make an impact.
The Serie A champions have lost four of their last five matches and are currently in fourth place.
