Yet the addition of another star striker in itself does not answer City's problems.
Although it was not one of their better displays, the Blues' goals against West Ham had the mark of class that has been stamped over most of their recent performances.
The involvement of Yaya Toure, David Silva and Samir Nasri in Sergio Aguero's opener was wonderful. Toure's stunning second, as skipper Vincent Kompany noted, will be replayed worldwide.
What City need is someone to pick up the slack when the main men are not firing. It is in that regard they have not been up to scratch.
Once a place in next season's Champions League is secure, Mancini may wish to use some of his fringe men to work out whether they are actually good enough.
Before that though, there is the little matter of a trip to Swansea and an FA Cup final to think about.
Roberto Mancini: "Swansea will be important because we need to get three points.
"It will be difficult but if we do then we can prepare well for the final."
