I haven't seen Inter parking the bus against a team for a long time. They have been used to playing with 3 defenders and an offense-oriented game at the same time.
Inter Milan aren't really an attacking team, of course they have their own way of approaching games and getting goals, but they are not the kind of team that holds possession and attacks constantly, they do not have the necessary quality in their squad to do that. Having said that, there's no doubt that Inter would park the bus against City, even most of the best clubs in the world would do that, when you come up against City you have to respect them and accept the fact that they would control most aspects of the game, Inter have to do one thing, defend and wait to hurt City on the counter.
