And it's no secret that Reds boss Arme Slot is eyeing leftback options for next season.
But Scotland skipper Robbo didn't get to where he is in this game by accepting being second best.
He has heard all the rumours down south. About how Liverpool are looking to find someone new in his position with Hungarian ace Milos Kerkez and Fulham skipper Antonee Robinson just two they've scouted.
But Robertson is used to it now. You get the feeling he thrives on the challenge revels in people doubting him.
Despite turning 31 just over a week ago, he's ready to prove his worth all over again.
Robertson admits to making a few uncharacteristic, individual errors this term.
That's what prompted Sky TV pundit Carragher to urge his old club to buy a full-back.
But given his body of work so far-he's won every major English honour at Anfield and is a Champions League winner - Robertson has every right to feel that he deserves more respect.
Tonight in Athens, he'll go up against his Liverpool team-mate Kostas Tsimikas, who he's managed to keep out of the team on Merseyside for almost five years now.
And after the disappointment of losing the Carabao Cup Final to Newcastle at Wembley last week, Robertson plans to shine on the international stage again.
When asked about his own form and the prospect of another left-back being signed by Slot in the summer, he was unequivocal in his response.
Robertson said: "I think we've been linked with pretty much every left-back in the world!
But listen, that comes with playing for one of the greatest clubs in the world.
"I look back on the eight years I've had at Liverpool and think I've been the starting left-back at the club. I feel a lot of pride about that.
"Eventually, your time comes. But I don't think it's my time yet.
"Even if we do bring someone else in, so be it. I'll always back myself. Sure, this season there have been a couple of moments when I haven't covered myself in glory. But some of the things have been blown out of proportion.
"I think my performance levels have been there. I've had a relatively good season and one thing people can say about me is that I've always been pretty consistent.
"But when you make a couple of mistakes, then people talk.
"That's the world we live in, that's the Premier League.
Everyone has eyes on you, everyone has an opinion.
"But I'm always confident in my own ability. I've shown that, right throughout my career-but especially during my time at Liverpool."
One thing's for sure, Robbo's importance to Scotland can't be underestimated.
That was proven in our last game when the captain rose magnificently in the last minute of our Nations League clash with Poland to head home a sensational winner.
That goal gave Steve Clarke's side this play-off shot against Greece to stay in the top tier.
