How are the two even comparable? Madrid fans boo their players almost on a weekly basis and that despite whatever they have achieved for the club. That scenario with us, was done only by a small group of Chelsea fans and that was a reaction to Mourinho's sacking, which we were right to sack him and those fans' reaction was silly.
I know what you're trying to get at but those examples are terrible. Clockwork and Sideshow Luiz are just resigned to losing Hazard, which I think deep down, we all have been feeling the same for some time now. That's different from actually criticizing him, is it?
