Giroud, whose existing deal expires in 2017, has struck 18 times this season and his representative expects the Gunners to offer the forward an extension in the coming months.
Michael Manuello told Calciomercato: "The rumours about Olivier are not surprising given that he is having a great season.
"I read about Juventus and Roma, but the truth is that there has been no contact with these clubs or with other ones. Juve were interested, it is true, but that was before he moved to Arsenal.
"He's very settled in London and the club is happy with him. I think there is no possibility he might change club. At the end of the season we will meet with the Gunners to discuss a contract extension."
The former Montpellier man has fired 35 goals in total throughout his two-year spell in the capital thus far.
