They sacked avb, beat napoli and a league one side in the cup and have now gone back to the average performances that saw them lose at city and barely had a shot against the scum.
Has the new manager syndrome worn off already and caused chelsea to revert to their normal form for the season? Watching them play yesterday it wasn't any different to the avb performances.
Maybe it wasn't avb's fault at all and chelsea just have an aging squad.
