I agree with this completely, and was thinking it for the last couple of seasons. I loved Eden playing for us, and I think he's easily the most talented player ever to pull on the blue, but in recent years we weren't as much a team as just a vessel for Hazard. If we tried to play fast attacking football it was great right up until it reached Eden who 4 times in 5 would slow down to walking pace and draw in the defender, while their team would have plenty of time to get back. It also felt like most of the time our attacks followed a fair narrow range of options, mostly tied around Eden and Willian short passing or trying to run their man.
Looking at the difference this year when we have some lightning fast attacks and real variation in attack, and its like night and day. We've lost our best player but my god we're so much more versatile and fun to watch now.
