Galliani is in the market for a new midfield playmaker and is keen to tempt Roberto to Italy.
The midfielder is regarded highly inside Spanish football, but his career is yet to catch fire while being part of Barca's star-studded squad.
Roberto has also been linked with a loan move to a Primera Division rival.
