Manchester City will be without John Stones, Ilkay Gundogan and Phil Foden for their pre-season visit to the USA this month.
Aymeric Laporte also misses the flight across the Atlantic. The reasons for their absence have not been disclosed, but all are expected to join up with the squad in time for the Community Shield clash with Liverpool on July 30.
It means Pep Guardiola has been able to stack his 26-man squad with youth. The unavailability of the aforementioned foursome also offers a fantastic opportunity for more senior players.
