Free agent Emmanuel Eboue must prove his fitness to earn a deal at Sunderland.
The Mirror says the former Arsenal right-back is a free agent after being released by Turkish side Galatasaray last summer, and is currently training with the Black Cats.
Big Sam is running the rule over 32-year-old Ivory Coast international Eboue as he continues to looks to strengthen in that area.
“Emmanuel Eboue has got a fantastic pedigree at Arsenal and if he has got any capability to produce what he did at Arsenal, we'll assess that over the next few weeks," Allardyce said.
“If we can get him fit, then he could produce the kind of performances that may benefit us."
