""My feelings will be mixed," claims Murphy. "If I score I'll be happy for myself and my club but at the same time it will give me no extra pleasure to beat Liverpool. I'm not someone who wants Liverpool to be mid-table. I want to see the club challenging for the title.
"I'll always be a Liverpool fan," he admitted. "I was before I joined the club and will be for the rest of my life.
"I've got to do a professional job for Charlton and do everything I can to win the game, but I'm not going there feeling bitterness towards Liverpool. I was treated fairly and honestly by Rafael Benitez.
"I'll always be coming to terms with the fact I've left Liverpool. I spent the best days of my career so far at the club. All my friends are there.
"It will be very emotional for me to go back but weird to be doing my best to make sure Liverpool lose.
"The three goals against Manchester United will always be with me, but my personal favourite was my goal against Everton in the Merseyside derby a few years ago. I remember at the time they were above us in the league and it was a massive game for us. I scored at a crucial time and that goal means as much to me as any I scored.
"I had a lot of good times as a Liverpool player and I'd like to think the fans recognise I always gave my best."
