Murphy said: "For me Euro 2004 is something I am really striving to achieve because I missed out on the World Cup with injury despite already being over there.

"This year I just have to make sure I do everything I can at club level to be selected and be involved in a big tournament.

There are probably five or six definites and maybe two or three positions in midfield that six or seven of us are fighting for. I have to make sure my form for Liverpool is right."
