The great Arsenal teams mentioned were the ones that I remember the most, incredible football that was a joy to watch even when we were on the end of it.
Napoli were another, at the time I hadn't rally seen anything like it, a back four, three holding midfielders and a front three that just ran at our defence with incredible pace while interchanging positions. I don't think anyone in our team knew what the hell was going on when they got hold of the ball. The interplay and movement of their attackers was incredible to watch, even though Klopp's teams go this route the way Napoli played it was a good two or three levels above Liverpool's interpretation of this system.
