The Reds signed the Scotland international from Hull City for a transfer fee of €9 million back in the summer of 2017.
Since then, Robertson has gone on to become a top player. The full-back is obviously a defender by trade.
However, Robertson has given Liverpool plenty of creativity in attack. He has scored six goals and registered 50 assists in 211 appearances for the Reds' first-team.
Therefore, it should come as no surprise that Williams, 20, has learnt a lot off "one of the best left-backs in the world".
As quoted by Anfield Watch's Twitter account, the Wales international told the Liverpool Echo the following: “I've learnt a lot off Robbo, him being one of the best left-backs in the world, you learn a lot from just training with him every day. He's a great character. Whatever you need help with, he's always there giving his honest answer.
“I have learnt massively off him."
Anfield Watch Verdict
It is great to hear that Williams is learning off Robertson. Senior players should always lead the way.
On another note, Robertson has made it clear in the past that he would like to finish his career at Anfield.
"Look, my aim is to finish at Liverpool, and I’d love to finish at Liverpool, but I know how tough it is to keep playing at the highest level," he said last year, as quoted by the Mirror.
"Time will come to make that decision. Right now I’ve still got a good length on my contract, I want to stay here forever and I hope to retire here."
Robertson, 28, is contracted until June 2026. If the Scotland international keeps on performing to a high level, then he could certainly finish his career with Liverpool.
But, as Robertson has stated, there is still a fair bit of time to pass before he genuinely considers retiring.
