'Insane' was the word Jurgen Klopp used. Roy Keane went for 'brilliant' among others when he ran the rule over him. Others have their own superlatives of choice when it comes to Trent Alexander-Arnold.
Walking out to a raucous Anfield on Thursday night for his 150th Premier League appearance, the 23-year-old can stand tall to make a solid case that, right now, he's the best there is at right back.
Even historically, nobody in his position has performed better over their first 150 Premier League games than Alexander-Arnold.
John Arne Riise, formerly of Liverpool, Ian Harte and Dan Petrescu are defenders who scored more goals than Alexander-Arnold's 10 across the 150 games, but add on his 43 assists and he's flying high as the No 1.
'I don't know anybody who is like Trent. Who is a right-back and is that decisive and influential and all these kind of things,' manager Jurgen Klopp beamed last month.
'I really don't like always when they mention his defending, "defensively he's not that good, but he's offensively better".
'The package of Trent is insane.
'It's not that he delivers every day, there are still departments where he can improve and has to improve and we will work on them and I will not stop telling him, but the package is really interesting, I would say.
'I'm not sure what it means in history. Still 15 years or whatever time to play and to create and to score and to learn and improve but the last five years were a good start in a career I would say.'
The numbers from his 150 league games, going back to his first team debut in 2016 as a sub against Middlesbrough, are remarkable.
Alexander-Arnold has created 300 chances for team-mates and has delivered 279 accurate crosses from that right side.
While stats are important, it is worth mentioning that Alexander-Arnold plays winning football, taking 105 wins from those 150 games.
And the narrative that he is a liability defensively struggles to stand given he has managed 50 clean sheets in the same period.
Add in too that across 150 league games he has been culpable for just two errors leading to a goal.
'[He's] absolutely brilliant,' hard-to-please Roy Keane told Sky Sports before Liverpool played Crystal Palace last month.
'What a player. Fantastic. The stats are absolutely brilliant, brilliant player, local lad bet he can't believe his luck. [The] chances he creates, the assists - unbelievable.
'[He] looks like a good athlete, a decent lad, a brilliant player and we all get excited about attacking players but to get excited about a full-back it's how the game's changed over the last few years. The full-backs are so important.
'The assists and positions he gets himself in, he's brave got a lot of courage - what a brilliant player.'
One of the biggest compliments that can be paid to Alexander-Arnold is that nothing seems to faze him.
Here stands a player that started a Champions League final at the age of 19.
He went on to win it a year later and secured a Premier League winners' medal a year later. Oh, and to top it off he's completely revolutionised the expectations for a modern-day full-back with his wing-man on the other side, Andrew Robertson.
The scary thing for Liverpool's rivals is that Alexander-Arnold continues to get better.
His role has changed somewhat this season as he is often seen drifting into the pocket of the midfield to assess his options, think about an NFL quarterback, given it is Super Bowl week.
Having the licence to break position and launch Liverpool on the attack is invaluable and it is no surprise he has already surpassed (10) last season's assist return (7) in the league.
His highest assist total in the league for Liverpool came in 2019-20 when he managed 13 with four goals. Midway through February this season and that figure stands at 10 and two.
It said it all that in the first 45 minutes against Leicester, Alexander-Arnold had created three chances.
For some perspective, Liverpool's other 10 players had managed to create two and the entire Leicester team had also managed just two.
'He's different to every full-back out there,' former Liverpool striker Michael Owen told BT Sport. 'He could play any position out there, he's that talented.'
One of the things that makes Alexander-Arnold so special is his delivery is, more often than not, spot on, particularly on set-pieces.
It is impossible to forget his quick-thinking from the corner in that Champions League tie with Barcelona at Anfield which gave Divock Origi an enviable tap-in.
And it is no surprise that Liverpool have scored the most goals from set-pieces in the Premier League this season, edging ahead of Chelsea.
Klopp's side have netted 12 goals from set-pieces this season - two more than Thomas Tuchel's Chelsea.
There was Alexander-Arnold's free-kick that was converted by Sadio Mane to kickstart an eventual 4-0 win over Arsenal back in November or the corner he whipped in for Virgil van Dijk to head in in a 4-0 win away to Southampton.
Liverpool have had their fair share of local lads done good - chiefly Steven Gerrard and Robbie Fowler - but Alexander-Arnold has ascended himself to greatness already.
And at the rate he is going, arguing against him as the best right back in the world may become a losing battle.
