Sunderland are chasing Manchester City striker Benjani Mwaruwari.
Black Cats boss Keane thinks he can land Benjani, 29, for £5million.
He moved to Eastlands only in January but new gaffer Mark Hughes wants added firepower, with his old Blackburn striker Roque Santa Cruz top of the hit-list.
Keane can offer Benjani first-team football and match his City wages of £40,000 a week.
