I honestly feel like one of the few people who appreciates both defensive-minded sides & Barca-style possession-based/attacking. Most seem to love one but despise the other, but I can be entertained by both to an extent.
For example, Barca entertains me, but Del Bosque's Spain side has been boring me since Euro 2012. There's a marked difference between the two.
And the traditional Italian defensive style =

, but Di Matteo's Chelsea (and frankly, Mourinho's treble-winning Inter) - not so much, strictly in terms of being "fun" to watch.
But in the end, it's still winning that matters, not entertainment. Which is why I don't get when people say a certain team didn't "deserve" to win the CL. If you scored more goals than all the teams you faced on the way (which is the objective of this sport, after all), you deserve it no matter what tactics or style you used.
