Beleaguered Chelsea manager Andre Villas-Boas has described his team's 2-0 defeat to Everton on Saturday as one of their 'worst' performances this season.

He said his team's toothless play against Everton at Goodison Park was devoid of any positives for his side.

"I think today was one of our worst games of the season, if not the worst. In our performance today we are short of anything positive. It is a difficult day for us, we take out a lot of negatives from this game," The Sun quoted Villas-Boas, as saying.

Steven Pienaar and Denis Stracqualursi scored the goals for Everton, while under-pressure Fernando Torres once again failed to find the back of the net.
