Roma have added Miralem Pjanic and Simon Kjaer to their squad ahead of the 2011-12 campaign.
Midfielder Pjanic arrives at the club on a permanent basis after a deal was agreed with French outfit Lyon.
Danish international defender Kjaer has completed his loan switch from Wolfsburg after some last minute problems were overcome.
Roma have yet to reveal the costs behind the operations.
The Giallorossi are also talking to the agent of Real Madrid midfielder Fernando Gago to agree personal terms.
The Argentine will arrive on loan if a compromise over wages can be reached. Roma will also have the option to buy him next summer for just €6m.
