It'll be interesting to see how much Abramovich is willing to invest. He's already just bought Luiz, Torrez, Meireles, Lukaku and now Marin. Hardly a small chunk of money - by my reckoning that's about £120m! And the squad STILL needs 5 new players? Ruddy hell.
Personally, I'd rather they make do with what they've got. McChecran (spl?) was supposed to be all that and feature heavily - the first promoted youth player since Terry - but we've not seen him. Lukaku was, surely one of the most expensive kids to be transfered ever - where is he? Chelsea also paid almost £10m for Piazon, who is still very young, but should be getting games.
The pressure on Chelsea managers for short term success is so high that they may as well not even bother having a youth team. If Abramovich is so keen on winning every year, he should just pony up the money to buy 'peak' players instead of worrying about developping them internally.
