The Black Cats have agreed a deal with Saudi Arabian outfit Al-Hilal to take 6ft 5in defender Mangane on loan until the end of the season and he is expected on Wearside over the weekend to discuss personal terms and undergo a medical.
Martin O’Neill has been desperate to boost his options at the heart of his back four during the transfer window after seeing Carlos Cuellar and John O’Shea join long-term absentee Wes Brown on the treatment table.
Martin O’Neill: “Centre-half is becoming a real problem to us at the moment.
“Carlos got injured last weekend, John O’Shea is only just back in training and Wes is obviously still a long way away.”
