Manchester City remains the only Premier League club to maintain a 100% record after beating rivals Manchester United at Old Trafford; Chelsea move into second after a draw in South Wales, and West Ham has troubles in more ways than one.

Manchester City is the only Premier League side left with a 100% record after Week 4 courtesy of a stunning victory against their inter-city rivals Manchester United, at Old Trafford.

It was the most eagerly anticipated Manchester derby game in modern times. The two best coaches in the world, some of the best players, and two 100% records to protect.

Both Manchester sides missed their star men in this one. Sergio Aguero started his three-match suspension for elbowing West Ham’s Winston Reid in Week 3. And you could be forgiven for forgetting Paul Pogba was on the pitch such was his dismal display in such an important early season rubber.
