Glasgow-born Robertson started of his youth career with Celtic and always planned on playing for the Bhoys.
Now a Premier League and Champions League winner with the Reds, the Scotland captain feels he has found a permanent home at Anfield.
"It's something that I think about quite a lot to be honest," the 26-year-old told The Lockdown Tactics podcast.
"As my career started to progress, if you had asked me at Hull would I have liked to have gone back up to Celtic I'd have said 100 per cent I want to play for the club I have supported all my life.
"Playing at this club is amazing the way you get looked after, the way the fans are, and playing at Anfield every second week is incredible. In an ideal world I retire here but I know how hard that is going to be.
