Alexander-Arnold and Robertson played together on 279 occasions – an average of 35 games a season in all competitions in their eight seasons together.
And each of them only played more games with Mohamed Salah.
Robertson joined from Hull City for £8m in 2017-18 with Alexander-Arnold, an academy product, having made his debut the season before.
They won 185 of those 279 games, losing 43 times.
The two full-backs played attacking roles in former boss Jurgen Klopp’s high-energy football – and had a hand in nearly unprecedented numbers of goals.
In isolation their assist hauls would be remarkable but the fact they were both doing it at the same time is even more amazing.
In March 2019 Alexander-Arnold told the BBC: “We both thrive off each other’s performances.
“We have got a competition between ourselves this season to see who gets more goals and assists. It’s a healthy competition.”
Only on 10 occasions in Premier League history has a defender created 10 or more goals in a Premier League season – and Alexander-Arnold and Robertson have each done it three times.
In 2019-20 they assisted 25 goals between them.
