Manchester City maintained their 100% record in the Premier League this season under Pep Guardiola with a 3-1 win over West Ham at the Etihad Stadium.

Goals from Raheem Sterling and Fernandinho rounded off a good day's work, but there was one sour note that came out of the game.

Sergio Aguero was involved in what appeared to be an intentional elbow on West Ham defender Winston Reid.

If he does receive a ban he could end up missing the Manchester Derby on September 10, the first where Guardiola and Mourinho rekindle their rivalry.
