Rooney, who left Goodison Park in Aug 2004, said: "I'm very excited about the match.
"I grew up an Everton fan, my whole family are Everton fans and I grew up hating Liverpool. And that hasn't changed," The Sun quoted him, as saying.
Rooney, 23, said: "Liverpool have been brilliant and put up a good challenge, but it will be great if on Saturday we can finally finish that challenge off.
