Sao is out of contract at French club Sochaux this month, according to Transfermarkt.com, and Championship trio Wednesday, Stoke and Reading are reportedly interested in securing the services of the 28-year-old this summer.
Sao started his professional club football career at Le Havre before moving to French rivals Sochaux in 2015.
According to The Sun, since joining Sochaux, the forward has scored nine goals in 68 domestic matches.
Sao has done relatively well in recent years, and given that he would be a free signing, one can understand why Championship trio Wednesday, Stoke and Reading would be interested.
