The France striker has scored 18 goals in all competitions for the Gunners this season, and has been linked with a move abroad following some off-field problems.
But the 27-year-old’s agent claims Giroud has no desire to quit the Emirates and is even working to secure a contract extension at the club.
“The rumours about Olivier are not surprising given that he is having a great season,” Manuello said.
“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.
