Sheik Mansour's money has brought a level of success to Manchester City that the club has never experienced before, at least in the modern era.
The noisy neighbours to Manchester United have made themselves into one of the Premier League's, and arguably Europe's, finest outfits.
Creating a dynasty
However, the club now need to take the next step in their development and start achieving consistent success in a bid to create a dynasty similar to that of Sir Alex Ferguson or, to a lesser extent, Jose Mourinho.

To do that City will need to sign players, but the type of player they need to purchase is one that I rarely see linked with them in the rumour mills.
Kevin De Bruyne is the player most heavily linked with a move to City, but I feel that if the Belgian were to move to the Etihad his signing would be simply a statement rather than a necessary acquisition.
City already boast the likes of David Siva, Samir Nasri, Jesus Navas and now Raheem Sterling in attacking midfield. Despite the poor current form of Nasri and Navas, on paper the depth is already high quality in Pellegrini's squad.
Area that needs strengthening
Where the quality in depth is at its poorest is without a doubt in central midfield. Yaya Toure proved on many occasions last season that the latter stages of his career at City should be spent further forward if he is to flourish.
Fernando's debut season in Manchester was best summed up as average, while Fernandinho failed to replicate the impressive form he displayed in City's title winning campaign of 2013/14.
The answer to me seems so glaringly obvious; City need a midfield enforcer. Someone to do the dirty work to a high standard and allow their wealth of attacking talent to do what they do best.
Some of you may cry for Paul Pogba, and there is no doubting the obvious talent that he is, but for me his talents would be wasted as the anchor man in a midfield. Offensively the Juve ace has too much to offer and would be wasted plying his trade protecting the defence.
The role of the defensive-midfielder is often underrated, but they are the players that can turn good teams in to great teams. Nemanja Matic has proven his importance at Chelsea, while Francis Coquelin's surprise form was a turning point in Arsenal's season.
They can sometimes be the difference, and when the going gets tough they provide the necessary discipline and steel to see the team through. Too many times last season City's midfield was easily bypassed. At Old Trafford it was arguably non-existent and we all know what happened there.
The hierarchy at the club need to stop trying to make marquee signings in positions already well stocked with quality and start addressing the areas of the pitch that suffered most last season.
Maybe after this issue is solved De Bruyne and Pogba would be good additions, but first quality depth is needed throughout the squad, not just in attack.
City fans, should Pellegrini focus on getting in a defensive anchor? Let us know what you think in the comments box below.
