Dzeko has started just 11 top-flight games this term, and he could be set for a move away from the Etihad.
As the final day of the January window approaches, we'll be tracking the 27-year-old's transfer gossip right here.
—LAST UPDATE: Thursday, January 30—
Edin Dzeko could be on his way to Borussia Dortmund, if reports are to be believed.
The Bundesliga club have been hit by injury this season and will lose striker Robert Lewandowski to Bayern Munich at the end of the 2013/14 campaign.
The Express' Ben Jefferson suggests that Dortmund may bid £17 million to bring Dzeko to Signal Iduna Park.
The Westphalia club are not able to match the Bosnian's £7m salary at the Etihad.
However, Dzeko has reportedly become despondent at City having fallen behind Alvaro Negredo in Manuel Pellegrini's pecking order, with the Spaniard having struck up an impressive partnership with Sergio Aguero.
And that could see the 27-year-old take a substantial pay-cut to push through the move.
Dortmund appear to have a long-term interest in the Manchester City man and were linked with a move for him in March 2012, as seen in the The Sun (subscription required).
Dzeko is proven in the Bundesliga, where he spent three and a half years with Wolfsburg, scoring 85 goals in 142 games.
Sergio Aguero might be facing a spell on the sidelines after limping off with a hamstring injury during Manchester City's 5-1 win against Tottenham Hotspur this week.
The extent of the Argentina international's injury is not yet known, but a potential absence from Manuel Pellegrini's side may have a bearing on Edin Dzeko's immediate future at the club.
In December, when Aguero was last injured, the Bosnian was called upon as cover, and early indications show that Aguero may have to miss out on facing Chelsea next Monday.
Pellegrini told BBC Sport:
We will see how he is after he has seen the doctor on Thursday.
He has injured his hamstring. Now we must wait and see how serious it is. We have tried not to depend on one player but we will always miss Sergio because he's a top player and we hope to have him again as soon as possible.
Sergio has just come back from a calf injury and when he didn't play we have Alvaro Negredo and Edin Dzeko and here we had Stevan Jovetic.
