Manchester City boss Manuel Pellegrini cannot rule out buying again this month.
Pellegrini has not ruled out making another signing before the season starts with a centre-back still top of his list.
Matija Nastasic is out of action until next month with an ankle injury and Micah Richards and Joleon Lescott have yet to agree new contracts.
"I'm very happy with the squad we have but if we think it's important we need another player we'll see next week," said the City boss.
