"We have played really well against Chelsea and defended strongly," Keane told evertontv.
“They are a good team with a lot of top-quality players, so we will have to be really on it like we were against Liverpool.
“Hopefully we can score a few goals, as well, and win the game.
“The derby was the best atmosphere I've played in at Everton. When the fans are like that it really helps us – but we know we have to play well to get them behind us even more.
“We will do everything we can to make sure we do that, we are really hungry for a win and need to beat one of the top teams at home – and we want to do that on Sunday."
