They are, and they are playing really well. No arguments there.
Up until two months ago they didn't really value possession for the sake of it though. They attempted the early, risky but potentially threatening, ball to either flank or to Mandzukic a lot. It meant less possession and more attacks from their opponents, but they gained opportunities to counter attack a lot more. I am not saying that this way of playing necessarily will be less successful, though it is highly likely after last season, but I think they are a lot less attractive to watch as a neutral.
