Anfield has not been without Champions League football since the 2016/17 season, but with the Reds sitting in sixth and four points off Chelsea in fourth with just five games remaining, their place in the competition next season is in serious doubt.
"This club is a Champions League team," the Scottish left back insisted.
"We got to the quarters-finals this year - and we are still disappointed with that - and two finals in the space of four years and won the Premier League comfortably last year, so to not have Champions League football next year would deflate the whole club, of course it would.
"This club is based on fighting to the end and that's what we need to do.
"Even if we win the next five games it might still not be enough but we need to put that pressure on the teams.
"There have just been too many games this season where we've dropped too many points. Against the bottom six, if you've only picked five points up at home then unfortunately you are going to fall short of your target."
