At the age of 31, Robertson is on the cusp of winning his second Premier League title medal - and will be aiming to lift the Carabao Cup for the third time when the Reds face Newcastle at Wembley.
Robertson said: “You see the age of the players who have been here a long time - and obviously there's a few of us in our 30s.
“At the end of the day, it always has to come to an end - but the lads have made it clear that they want to continue here with this fantastic club.
