Chelsea's defeat to Porto on Tuesday night wasn't entirely surprising given the way the Premier League champions have started the season.
The Estadio do Dragao is never an easy place to go but based on last season's form, you'd have expected the Blues to have come away with at least a point.
Andre Andre opened the scoring before Willian’s brilliant free-kick levelled things up right on the stroke of half-time.
But the Premier League champions looked all at sea defensively in the second period and one particular lapse allowed Maicon to nip in at the near post and secure victory for the hosts.
What can we take away from this performance?
