'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.
