The great Dalglish is the only man to have pulled on the navy blue of Scotland more times than Robertson.
‘King Kenny’ still tops the list on 102 caps, but that could be eclipsed by his friend come November should the 32-year-old feature in each of Scotland’s remaining three Nations League games this year.
It is fitting that it will be Robertson who surpasses that long-standing milestone, given the pair have forged a friendship over his time with Liverpool.
Not that Dalglish is having that.
“He always says ‘you’ve got millions more games; Nations League, what’s that? They didn’t have that in my day!'” Robertson joked on the Stick to Football podcast recently.
“I think he might bring up a ratio for years-to-games-played so he’s still on top.
“It’s obviously something that’s been on my radar for a while now. When you get to 80-odd caps, you start to look up.”
Dalglish can console himself that his record of 30 goals – held jointly with Denis Law – is safely out of Robertson’s reach.
Of current players, John McGinn is lurking only eight behind Robertson on the all-time list, though, so the Scotland men’s centurion club could have three members soon.
