Villas-Boas: Everton defeat was Chelsea's worst performance of the season

Andre Villas-Boas has admitted he made mistakes during Chelsea’s 2-0 loss to Everton.

Goals from Steven Pienaar and Denis Stracqualursi were enough for the Toffees to secure a win against the Portuguese’s side.

And the former Porto coach claims his players could not have put any more effort into the match.

“I’ll reflect hard on my preparations,” Villas-Boas said. “I’ll take full responsibility for the defeat.

“The players did everything they could to try and get the result. Maybe I need to look retrospectively at what I did and think about the preparation.

“It was our worst performance of the season. We just couldn’t be ourselves and express ourselves.”
