Skipper John Terry has accused his Chelsea team-mates of falling well below the standards required of them during Saturday's 3-1 defeat to Wigan Athletic.
The Blues lost their 100 per cent start to the season at the DW Stadium and afterwards the Stamford Bridge captain ripped into his colleagues.
Chelsea also had goalkeeper Petr Cech sent off on an afternoon to forget for new manager Carlo Ancelotti.
"The least we expect from every player is that we work hard and fight - and we did not do that," he said in The Sun.
"We didn't win our headers and we didn't win our tackles - and that's simply not good enough.
"You can go anywhere and not play well. But when you come to places like this, you've got to match their work-rate.
"We didn't do that, the whole team. That's the most disappointing thing.
"All the other big sides had emphatic wins, so it's even more disappointing we've thrown away three points."
