Rose names Robertson as Europe's best left-back
In an interview with The Lockdown Tactics podcast, Rose claimed that the Scot is "a freak of nature."
The on-loan Newcastle man said: "His consistency levels are extremely high. He is just brilliant.
"He’s been the best left-back in England and, maybe, Europe for the past two or three years. Easy.
"For me, now, he is the one I’m looking to catch, without a doubt. He is the best."
Rose has earned 29 caps for England since making his debut in 2016. He also made 214 appearances for Tottenham before joining Newcastle on loan in January of this year.
This proves that the Yorkshireman is in a great position to judge the world's left-backs.
And very few could argue with his claim.
Robertson has proved to be one of the league's best ever bargains since joining The Reds from relegated Hull City in 2017.
In his 119 games since signing, Robertson has 25 assists, a remarkable return.
His 11 assists in the 2018/19 season is only bettered by teammate Trent Alexander-Arnold in terms of assists in a single season by a defender in the league's history.
The pair's importance to Liverpool is detailed here.
He also adds defensive nous to his attacking ability.
He has been a key part of a Liverpool defence that has been the best in England in two of his three seasons at the club.
Going both forwards and backwards, Robertson is a truly elite fullback.
While Rose himself is no longer in the conversation about the world's best left-back, Robertson does have some contenders.
Jordi Alba and Marcelo have been two of the best left-backs in world football for the last decade or so.
However, both are past their peak. Marcelo, in particular, has been ousted by Ferland Mendy in Madrid. Mendy himself comes closer to Robertson that many others.
Many will point to Bayern Munich's Alphonso Davies.
He has had an outstanding season in the Bundesliga, without a doubt. But the converted winger has played only 21 games at left-back.
Despite appearing bullish about his position change originally, Davies has since claimed that his future may be in defence.
Yes, at 19 years old, he has loads of time to improve. But in the here and now, he is nowhere near Robertson's level.
The reality is that many fans outside Germany are basing their opinion of him solely on his admittedly fantastic performance against Chelsea in the Champions League.
Ultimately, Liverpool's Scottish hero has to win out.
