Torreira became an instant fans favourite with his combative performances after joining from Sampdoria last season, and made 50 appearances in all competitions, scoring two goals.
This season, Torreira has been switched from his favourite holding midfield position to a more advanced role.
Torreira has made just four Premier League starts to date as Emery continues to pick Matteo Guendouzi in front of his defence.
Bentancur says his 23-year-old client is discontent with his current situation at Arsenal but despite interest from other European clubs, he is not thinking about an exit from England yet.
Bentancur told Calciomercato: “I must say that the change of role has penalised him sharply.
"He is no longer at ease and we hope that things can change.”
"We have no problem with Arsenal but only words of thanks. Arsenal has allowed Lucas to compete in the Premier League, he has always shown great confidence.
"Clearly the interest for Torreira are all right, especially by Spanish clubs, but I have never sat down with any club to talk about his transfer.
"This is because of the great respect we have for the Gunners and general manager Raul Sanllehi.
"I don't want to name the teams out of respect, but I can tell you that Atletico tried to take Lucas from Sampdoria two years ago.
"There was an interest [from AC Milan] as well as other clubs.
"But we got together with the Gunners' general manager, Raul Sanllehi, and he immediately told us that for Arsenal, Torreira was not for sale - an adamant position.
"I also have to say that Milan did not present a real concrete offer."
