The Manchester City manager says the club are still in the market for new players to strengthen their squad.
The reigning champions have already signed Fernando, Willy Caballero and Bruno Zuculini this summer, but those deals are a far cry from the spending we have seen City from in past transfer windows.
This could be mainly due to the £49million transfer budget restriction placed on them for breaching the financial fair play rules set out by UEFA.
However City still have room to manoeuvre in the current window with the three deals completed already totalling only around £18million.
That would leave City with £31million plus any extra funds obtained from player sales. The likes of Scott Sinclair, Micah Richards, Jack Rodwell and James Milner could potentially leave City this summer.
At a press conference in Kansas, the City boss said: "I don't think the squad is complete yet but we have six weeks before the transfer window closes.
"Perhaps there is the option to bring one or more players in or maybe one or two will leave our squad but there is time for us to consider what is best for our team."
According to the Manchester Evening News, City are currently in talks with Porto over deal to bring promising young French defender Eliaquim Mangala to the north-west of England. Though completing a deal for the £30 million-rated man is still apparently someway off.
City might also be in the market for new striker with Sergio Aguero's proneness to injury, and the news that Alvaro Negredo will miss the next three months after breaking his foot in a pre-season friendly against Hearts.
