People keep saying, "Roman wants us to be self-sufficient", but how? You can't just stop funding and hope your club will become self-sufficient, you have to put money into scouting networks, youth facilities, buy youngsters (Ok they've been doing that recently but to be honest, it may turn out to be too little too late) etc.
Chelsea's youngster are nowhere near the quality of Man United youngsters (and trust me, I hate Chelsea and Man Utd equally). Man Utd atleast give their youngsters first team experience, Welbeck, Macheda and Simpson are all out on loan, Gibson was on loan too (although I think Gibson is ****). Those players have all had first team experience in the Man Utd side too.
