He told the News of the World: "I've won every major honour at Liverpool except one. It hurts more and more not only to have never won the league, but to have never really gone close.
"It would be bad enough if we only narrowly missed out on the title, but we've never got to March or April recently and thought we were in contention.
"That's what we want more than anything at Anfield, but we'll only achieve that when everyone is working together for the same goal.
"I watched United last week and as a Liverpool fan it killed me to see them win the league again.
"They deserved to win it and I have the utmost respect for their achievement, but we've got to do everything we can to get it off them next season."
