Everton manager David Moyes admitted his players deserved to be booed off the pitch at full-time following Wednesday's 1-0 Carling Cup third round defeat to Blackburn Rovers.
The Toffees' inconsistent start to the season continued as they lost out to a goal from Martin Olsson after ten minutes at Ewood Park.
Moyes had named a strong line-up and Jack Rodwell had a goal disallowed for a foul on substitute keeper Jason Brown, but afterwards he sided with the fans who gave his side a hostile reaction at full-time.
"They were entitled to do that because we did not play well enough. It was deserved," said the Scot.
"My reaction is whatever the supporters did they were right to do so. The players have done well the last season or two so they know what is needed now.
"It was a disappointing performance. We put a strong team out to go through, but unfortunately we did not do enough.
"But I have to give Blackburn credit. They played well and Tugay was the best player on the pitch.
"He controlled the game, especially in the first half, and we should have played much better."
