The 21-year old is widely expected to play a more active role in the Barcelona first team this season, having been an integral part of the "B" squad since 2009.
Roberto's first pre-season with the senior team coincides with the arrival of new boss Martino, following Tito Vilanova's resignation, and the midfielder is excited to train with the former Paraguay manager.
"He did a great job with Paraguay and with Newell’s," Roberto said to the club's official website.
"He’s a manager who has confidence in young players and his teams treat the ball well. Therefore, I think he’s the ideal manager for us."
The former Spanish Under-17 international also spoke about the departure of Thiago Alcantara, expressing his hopes for playing time in the wake of his compatriot's decision to leave.
"It’s a shame Thiago left because he’s a good player," Roberto stated.
"I wish him the best at Bayern and personally, I’m eager to see how many minutes I get on the pitch this season."
