You really should have criticised Roman for what he did. All the supporters had a chance to show their discontent. Your banner should have said "Abramovich out" for f*ck's sake.
CHELSEA IS YOUR CLUB. TAKE BACK CONTROL!
He is not going to just run away because of that. You keep quiet and he thinks he is totally untouchable and he can do what he wants. E ven owners have take the views of the supporters into account some of the time . What's the worst than can happen? You get new owners. At least you as supporters of Chelsea you get some dignity back. At the moment he treats you worse than dirt. You just do not matter to him.
