It's a bit more than a 1 man team but Hazard is massive for them from an attacking point of view. Without him they are very weak creatively but you also have Alonso and Kante who have been key players but in terms of the playing style this season everything revolves around Jorgino who is the hub of the team.
They are producing world class young players but it seems the academy is structured with a buy, develop, sell structure rather than buy, develop, use. However, in the last 2 seasons young players are starting to get more of a chance in the first team.
I think the early season form mislead people the bubble has burst a little bit but we saw vs City that they can be very dangerous and they really should have beaten Liverpool earlier in the season as well. Early in the season the chances they were giving the opposition were not being punished now they are and teams have probably worked out how to keep Hazard under control a bit better.
I think in the big games where it's back and forth they are fine but against the weaker sides they remind me of Utd under LVG lots of passing but not really going anywhere they haven't quite worked out how to have that cutting edge and break though teams.
The ground is on hold due to the owner's residency issues he's not prepared to spend £1bn developing the ground and surrounding area if the government aren't going to give him a visa to live here so it sounds like that's all been shelved.
As for players going there they go because Chelsea still pay good wages compared to clubs in europe, they still win trophies and London attracts players as it's a great place to live if you've got a lot of money. The training ground and facilities are also world class plus they know it's often a quick stop along the way it's not a club where players stay for ages they pop in and out for a few years.
