The 28-year-old Senegal international is expected to leave Stamford Bridge before Monday’s transfer window deadline following the arrivals of Samuel Eto’o and Willian this summer.
And Ba’s former clubs Newcastle and West Ham have been linked with moves to re-sign him throughout the summer, as both Alan Pardew and Sam Allardyce desperately seek to add strength to their attacking options.
But Roma look set to emerge as serious contenders for his signature as they plan to pair him up front with former Arsenal striker Gervinho, who they signed earlier in the transfer window.
Demba Ba made an instant impact when he arrived in England in 2011 when he scored seven goals in 12 Premier League appearances for the Hammers. But he activated the relegation release clause in his Upton Park contract, after Avram Grant’s side departed for the Championship, and joined the Magpies on a free.
After two seasons at St. James’ Park, where he scored 29 top-flight goals in 54 appearances, Ba joined Chelsea for £7million, but the forward has since failed to make a positive impact at Stamford Bridge having scored just two Premier League goals in 15 appearances since January this year.
