Despite being heavily involved during his two years at the Emirates Stadium, it has been well documented that the 24-year-old would prefer to return to Serie A.
Speaking to Calciomercato, Bentancur said: "There are many requests for information, but nothing official yet, so there are no written offers on the table.
"The player is training with Arsenal, they own him, he is one of the few cases of athletes who arrive in England and immediately play 50 games in a row. After a nasty injury, he didn't require surgery, but the recovery process was still tricky and took a while.
"Now the coach and Arsenal must work out if they need Torreira or not. Football has to be divided into two parts, the sporting and the economic areas.
"In sporting terms, Torreira is perfect for Torino and he'd reunite with Marco Giampaolo after their time at Sampdoria. At the same time, we must be realistic and admit Arsenal will have some very big demands, while Lucas's salary is also a bit too high for Torino."
Torreira did not feature in the squad for Saturday's Community Shield win over Liverpool.
