The injured pair missed most of December and with Stevan Jovetic also absent for several games, David Silva, James Milner and Jose Angel Pozo filled in up front at various points.
Dzeko had only recently returned from an injury sustained away to QPR in early November when he picked up a calf strain in the warm-up away to Leicester a month ago.
