I think Chelsea has made it much easier to be a Chelsea-hater, that's for sure.
On the one hand, I do have a revulsion over the concept of buying your way to a championship (Inter's track record keeps me hopeful that the Scudetto and CL aren't just up for the highest bidder). I also think that what Roman has done is create such an inequity in the game, that already was making little viable financial sense, that he is watering the seeds of the sport's economic demise.
But to hate Chelsea on other merits? I can't say it's happened to me yet. It's not like Real Madrid, where their player acquisition goal has clearly been more to sell jerseys to Asians than it has to field a complete and competitive squad. ManU has hand-over-fist money and can spend it like drunken sailors (see: Rooney), but I do admire how they have been open to bringing in young talent such as Ronaldo, Fletcher, Spector ... at least they take some risks.
Chelsea has a lot of players I admire ... and I'm sure that has a lot to do with my following of the Portugal NT. Mourinho is arrogant, but he can at least back it up. And how he dealt with Ferguson in last season's CL was legendary.
And teams that win and are successful are always going to gain both fair-weather fans and vehement critics. Juve is no exception. But for all the teams that aren't top-dollar successful out there that I do follow -- AC Parma, Sampdoria, Everton, Norwich, Villarreal, etc. -- there just isn't the TV coverage, online forums, club merchandising, etc., that makes it all that easy to follow them that closely. So it's only natural that the big clubs get my, and our, attention. Chelsea's no different.
Though for the record, I was more a Juve fan after that CL final with Milan than before it.
