Sergio Aguero is set to miss the start of the Premier League season, with Manchester City likely to be without four of their South American stars.

Martin Demichelis, Pablo Zabaleta, Aguero and Fernandinho have not been on City's preseason tour to Australia, having been given time off after the Copa America.

Manager Manuel Pellegrini has admitted they are unlikely to feature when City kick off their league campaign away to West Bromwich Albion on Aug. 10.

The Chilean believes it is vital his players have enough of a summer break, even though he may have few options for the start of the season.

New signing Fabian Delph could also be a doubt for the Albion game after injuring his hamstring in City's 4-1 defeat to Real Madrid in the International Champions Cup in Melbourne.

"I think in football it's so important to work hard, but also resting has the same importance," Pellegrini told reporters.
