Gunners boss Arsene Wenger is known to be keen to strengthen his defence in the summer, with Phil Jones of Blackburn Rovers and Paris Saint-Germain's Mamadou Sakho both on his radar.
According to the People, he may have to extend his search for defensive reinforcements as Roma are lining up a bid for Sagna.
The Serie A club are said to be willing to pay €6.73 million for the right-back and to offer the 28-year-old a lucrative four-year contract.
Should Wenger agree to sell, he could move for Montpellier's Yanga-Mbiwa.
Arsenal scouts have been keeping a close eye on the 21-year-old in recent months as they decide whether to make a bid, reports the News of the World.
The €8.97 million-rated France Under-21s international is versatile enough to operate at right-back and provide cover for central defenders Thomas Vermaelen and Johan Djourou.
Yanga-Mbiwa, who has already played more than 140 times for Montpellier, is also believed to be a target for Bayern Munich and Barcelona.
