Ferran Soriano has said that City's transfer dealings will conclude with the signing of a new defender.
The Premier League champions' transfer dealings haven't been as extravagant as we're used to seeing this summer.
Financial Fair Play has restricted City's expenditure this window, with the blues having only spent £19.5 million so far.
They have added Brazilian holding midfielder Fernando Reges for £12 million, Argentinian's Willy Caballero at £6 million and Bruno Zuculini at a cost of £1.5 million, with Bacary Sagna joining on a free transfer from Arsenal.
City's main goal this summer has been to recruit a centre-back who can establish a long-term partnership with skipper Vincent Kompany. Porto's Eliaquim Mangala and Roma's Mehdi Benatia have been consistently linked with a move to the Etihad, with a deal for Mangala currently looking the most likely.
He told the Men In Blazers podcast: "We don't plan season by season, we plan in cycles. And cycles can be three, four, five seasons. One year ago, we knew the positions we wanted to reinforce in the team and we did it.
"We have a new right-back, we having a holding midfielder, we'll have a new central defender and that's it. We don't need to sign new players for the sake of it.
"We need to sign players that the team needs because the team has a balance. To win you need to keep the balance.
"Our squad is very strong and it's the second year that they play with Manuel Pellegrini, so they'll do much better."
