The game isn't over yet but this kind of early goal scoring is something that's been lacking in City's game for a while. It is also worth noting that it is a strong habit of Manchester United to score lots of goals later on in the game. What is interesting is that now, Man City seem to have a composure and poise that they didn't have last season. And even though this is a 'friendly' game, it has all the grit and determination of top flight football.
Hopefully City's luck will turn in the new football season and Man Utd's star will fall in favour of a strong new team with the motivation to win the premiership.
