With the completion of Dzeko's transfer on Thursday morning, City have now spent in excess of £300m on players. The former Wolfsburg striker is the second most expensive transfer in the history of the Eastlands outfit after the previous capture of Robinho in the summer of 2008 for £32.5m.
The 40-year-old Mansour bin Zayed paid £210m for the initial take-over of City and then spent a further £20m on stadium and training ground improvements, thus taking the amount of money spent on the Premier League side to £570m.
However, the biggest expense for Mansour bin Zayed so far has been the wages for new players and those on existing contracts. Well over £500m has left the Sheikh's bank accounts in the past two-and-a-half years to pay the players and other staff at the club.
Below are the major purchases since the heavy injection of cash since 2008, and as predicted, some signings have turned out to be more astute than others.
Robinho£32.5 million from Real Madrid - September 2008
The Brazilian arrived at Eastlands with a huge reputation but the playmaker struggled to adapt to life at Eastlands. Having been shipped out on loan to Santos, the 26-year-old returned, made it clear he wanted a move away from the Premier League, and was sold to AC Milan in August 2010.
Wayne Bridge£10 million from Chelsea - January 2009
The left-back only cemented his place in the side for one season and this term the former Stamford Bridge man has found himself out of the team.
Craig Bellamy£14 million from West Ham United - January 2009
The Welshman linked up with Mark Hughes once again and was arguably's City's best player last season. But rows with Roberto Mancini damaged their relationship and the forward is currently on loan to Championship side Cardiff City.
Shay Given£7 million from Newcastle - January 2009
After joining the club as a first-choice goalkeeper, the Irishman has now found himself behind Joe Hart in the pecking order.
Nigel de Jong£17 million from Hamburg - January 2009
Arguably, this has been City's best signing. The combative defensive midfielder has become an inflential figure in Roberto Mancini's title challenge.
Gareth Barry£12 million from Aston Villa - June 2009
Despite reservations regarding his quantity of playing time, the midfielder has enjoyed a prominent role in City's side since his arrival.
Roque Santa Cruz£16 million from Blackburn Rovers - June 2009
Despite his scoring record with previous clubs, the Paraguayan has never been able to string together a number of games since arriving at Eastlands and Mancini has told the striker he can leave the club.
Emmanuel Adebayor£25 million from Arsenal - July 2009
Upset the fans of his former club by celebrating in front of them after running the full length of the pitch to do so. Hasn't convinced at Eastlands since his arrival and his work rate has been overshadowed on occasions by Tevez.
Kolo Toure£15 million from Arsenal - July 2009
Jumped ship along with Adebayor but unlike the Togo striker, the centre-back has slotted in well at Eastlands.
Joleon Lescott£22 million from Everton - August 2009
Plagued by injury and inconsistent selection, the defender has struggled to cement a regular role in the first-team.
SylvinhoFree from Barcelona - August 2009
The Brazilian arrived at the club purely as a back-up option to Wayne Bridge. After making a handful of appearances, City released him in the summer of 2010.
Patrick VieiraFree from Inter Milan - January 2010
Mancini's first signing, the defensive midfielder has performed well when called upon and undoubtedly brings experience to the dressing room.
Adam Johnson£7 million from Middlesbrough - January 2010
A deadline-day signing for Mancini, the 23-year-old was the first in the Italian's policy to sign young English talent. Has done reasonably well during his time at City but has not been given as many opportunities as first hoped.
Jerome Boateng£10.5 million from Hamburg - June 2010
The 22-year-old was hampered by injury during the start of his career at City but since his return to fitness, the defender has showed promise.
David Silva£26 million from Valencia - July 2010
The winger has performed well whenever he has started but appearances have not been as consistent due to injuries and squad rotation.
Yaya Toure£24 million from Barcelona - July 2010
Has quickly established himself in the side since arriving at Eastlands alongside Gareth Barry and Nigel de Jong but Mancini has elected to play the midfielder in a more advanced role and the Ivorian has flourished in this position with his excellent distribution and physical prowess.
Aleksandar Kolarov£16 million from Lazio - August 2010
The left-back picked up an injury during his debut against Tottenham but since his return, he has made the left-back role his own.
James Milner£26 million from Aston Villa - August 2010
Has failed to live up to his high price tag but has not been handed a consistent run in the side by Mancini which has hampered his progress. His versatility could be a double-edged blessing as he has struggled to hold down a single position.
Mario Balotelli£24 million from Inter - August 2010
The Italian has lived up to his image by not only donning garish headwear but insisting he already fancies a move back to his home nation at some point. His loyalty may be questionable but on the pitch, his performances have been superb and eight goals in 11 appearances this term have proved the striker has much to give.
Edin Dzeko£27 million from Wolfsburg - January 2011
The striker comes with high praise from just about every corner and whether he will slot into City's system with ease remains to be seen. It will be interesting to see how Mancini will rotate his striking options and maintain a happy camp.
