Glenn Hoddle accused Chelsea of lacking leaders after they suffered a second-half collapse on the way to booking their place in the Europa League semi-finals.
Maurizio Sarri's side beat Slavia Prague 5-3 on aggregate after a 4-3 win in Thursday's second leg at Stamford Bridge.
Having raced into 4-1 half-time lead, Chelsea made hard work of it in the second half as Slavia Prague capitalised on some lax defending to haul themselves back into the game.
It's not the first time Chelsea have struggled after the break this season and following the game, former Chelsea boss Hoddle lamented their latest second-half slump, as well as their failure to replace the leadership of John Terry.
'They can't get 90 minutes' consistency, you can't dictate 90 minutes anyway but they do switch off, almost as if, "We're too good for this team, I don't need to get on the cover",' he told BT Sport.
'It's complacency a little bit and they need a leader out there that's not going to let that happen. John Terry, in that team tonight, that wouldn't have happened second half.
'They haven't got many leaders there that can identify and put it right and say, "Let's put it right". You could smell it happening, your opponents are getting more of the ball, throwing people forward, you need to nullify that and someone needs to identify that.'
Hoddle, meanwhile, suggested Chelsea's players are guilty of passing the buck and relying on others to clear up their mess.
He added: 'Everyone just left it to one another – “Someone else will do it today, I won’t bother to get on the cover early because we’re 4-1 up”.'
'No I’m sorry at this level or any level of professional football, bang bang, you lose two goals and then you’re on the knife edge.'
