Ultimately, so long as you score more than you concede, it doesn't matter.
How that's achieved is for individual managers and teams to sort out.
Dour, overly conservative play doesn't keep fans on the edge of their seats.
However, it's clearly a fashion for teams to play around at the back, which as we know sometimes results in a goal conceded.
City are now utilising a long ball more to compensate for teams pressing them, and no doubt it will become fashionable at some point to be a bit more defensive and use the longer ball again if it starts to work regularly.
