The Brazil international has been linked with a move to European heavyweights Paris Saint-Germain, Chelsea and Real Madrid, though he has been included in the squad to face Vaslui in the Europa League play-offs this week.
Nevertheless, Stramaccioni has refused to comment specficially on the transfer situation regarding the full-back, instead revealing that there would be transfer activity to come.
"In my view, Maicon is the best in the world, but obviously there are different evaluations to be made, as there is more than just fondness or monetary value," the young manager told Sky Italia.
"All of Inter cares about the Brazilian, as he is a fantastic lad. We'll have to see what happens. This Inter side does need to be completed, that is beyond doubt.
"Something will certainly happen before August 31. In fact, I'd say before August 26."
