Andre Villas-Boas was in no mood to look for excuses following a match that leaves Chelsea without a Premier League victory for over a month.
The Blues were condemned to a 2-0 defeat against Everton at Goodison Park, after falling behind with just five minutes on the clock when Steven Pienaar scored on his first start since his return to Merseyside.
As Villas-Boas looked for a response from his players, a limp performance was made even worse when Denis Stracqualursi doubled the Toffees advantage with a little under 20 minutes to play.
"I think today was our worst game of the season, the worst in every sense of the word," claimed the Portuguese tactician. "Everton were fantastic today, their new signings have helped them improve a lot.
"In our performance we were short of anything positive, it's a difficult day, there were a lot of negatives to take from it and a lot of things we need to improve on bearing in mind the FA Cup and Champions League."
Chelsea enjoyed long spells of possession yesterday, but a lack of cutting edge in the final third did little to inspire their increasingly blunt attack.
"We suffered early in the game and though we controlled possession to the end of the first half we couldn't create enough chances," Villas-Boas continued.
"The second half was very even, but it was physical and we couldn't create enough chances, so in the end it was a lack of clarity that punished us hard.
"At the moment we are fifth and that's not enough for us. We played with Mata between the lines when I brought Essien off but they scored straight away so I decided to put three strikers up front, and that was the logic behind my thinking."
