Pep Guardiola has refused to rule out a late move for Leicester defender Harry Maguire.
Manchester City have been linked with the England international following Vincent Kompany's departure to Anderlecht.
City have Aymeric Laporte, John Stones and Nicolas Otamendi as options at present with Eliaquim Mangala also still at the Etihad, although he is likely to depart before the end of the window.
Manchester United are also interested in Maguire with Leicester boss Brendan Rodgers confirming two bids from unnamed clubs had been rejected.
And despite not closing the door, Guardiola insists he would be happy with his current options.
“If we believe we can, if not we will survive without a new central defender," the Manchester City boss said.
City have brought in Rodri in a club-record deal from Atletico Madrid this summer while left-back Angelino has also returned to the Etihad.
Guardiola is not expecting a busy end to the transfer window with former Barcelona defender Dani Alves again linked with a move.
Asked if he expects more signing to arrive, he said: "No, not many. I like the faces that we have.
“Maybe but the transfer market is so difficult and the team is good enough. Maybe zero, maybe one, maybe one and a half.”
City closed their pre-season campaign with a 3-1 victory over Yokohama with Kevin de Bruyne, Raheem Sterling and Lukas Nmecha on target.
City face Liverpool in the Community Shield at Wembley next week.
