Mario Yepes is out until March due to injury.
"In defence we have got Philippe Mexes back so, despite the injury to Yepes, we think we can manage without bringing in a new defender.
“The good news for the midfield is that Gennaro Gattuso should be back in January and then Mathieu Flamini will also return.
“We are just missing an element numerically in attack. We wouldn’t have done anything had Antonio Cassano not had his problem,” said Galliani.
