Onuoha adds to City's growing injury list
Manchester City defender Nedum Onuoha is set to be sidelined for around a month after suffering a calf strain.
Onuoha suffered the injury during Saturday's 4-3 win over Sunderland and tests have revealed that he will be out for three to four weeks with the problem.
Onuoha joins fellow defender Joleon Lescott on the injury list and, with Shaun Wright-Phillips and Emmanuel Adebayor both doubtful for the Boxing Day clash, new manager Roberto Mancini admits the growing list of absentees is a concern.
"The only problems I have are not who we might buy in January, but that we have too many injuries," he said.
