Manchester City have been given a potential fitness worry ahead of the start of the Premier League as Sergio Aguero, Samir Nasri and David Silva were all sent home from training after suffering with a virus.

All three missed the club's annual awards ceremony, City Live, in an unwanted disruption to their build-up.

But as City's first game, away at West Bromwich Albion, is not until Monday, they have five days to recover.
