“No one wants to grow up and be a Gary Neville,” Jamie Carragher quipped regarding his co-pundit on Monday Night Football back in September 2013.

“If you’re a full-back, you’re either a failed winger or you’re a failed centre-back. You end up there by hook or by crook.”

Gianluca Vialli, the former Italy and Chelsea forward, echoed that sentiment, positing the right-back was always a team’s weakest link, given left-footers were cultured.

If you had something about you and were right-footed, you would either play at centre-half given your height or further forward, so the theory went.

Trent Alexander-Arnold was a month shy of his 15th birthday when Carragher delivered those now infamous words.

But ask any child of a Liverpool persuasion this week – as the champions-elect prepare to host Manchester United, live on Sky Sports – who they wish to one day emulate, and the local boy with the double-barrelled name will rank high upon that list.

It was last October when Neville highlighted the rise of Alexander-Arnold as the flag-bearer for the modern-day full-back.

Tottenham had been beaten 2-1 at Anfield, a game in which Liverpool’s right-back had failed to register an assist but had been a constant source of creativity for the hosts.

“Liverpool’s full-backs are quite simply sensational,” Neville told Sky Sports. “Trent Alexander-Arnold is amazing.

“From the moment I laid eyes on him in that first game at Old Trafford [in January 2017] his temperament was amazing. To be thrown in during that game, he was outstanding from minute one.

“But now, he’s getting to a point where he’s one of the best full-backs I’ve ever seen going forward – his passing is unbelievable. He’s got to become as serious about his defending as he is about his attacking, and then you’ve got a world-class full-back there.”

With his balletic movement, quick thinking and laser-like vision, Alexander-Arnold has taken his game onto new heights.

There have even been suggestions Liverpool’s No 66 should be played in a more advanced position, with a view to potentially replicating Gareth Bale’s transformation into a goalscoring forward.

Given the chances he creates from his right-sided berth, however, and the improving defensive record this season following six successive clean sheets, Jurgen Klopp is in no hurry.

Can United’s counter-attack expose space in behind?

What Alexander-Arnold may sometimes lack in concentration and defensive positioning, he more than makes up going in the other direction, producing more assists and open play crosses than any other Premier League player since the start of the 2018/19 campaign.

Speaking earlier this season, Graeme Souness admitted that at 21, and with still just nine England caps to his name, Liverpool’s academy product will get better defensively through being faced with stiffer opposition.

The Sky Sports pundit said during the autumn: “Trent’s five years younger than Andy Robertson, he’s not the finished article when it comes to defending, but has he learned in the last couple of years that part of his game?

“Maybe it’s because he spends so much time on the front foot. They’ve got such good players around him, that he’s not asked to do much at the other end, but it will cost them at times.

“That’s a part of the game you can learn, the easiest part. What’s he’s got in abundance is athleticism, and he’s got a wand of a right foot.

“He can whip the balls in when he gets into the attacking half. He’s a very special player, who will only get better.”

Contrary to Carragher’s slightly tongue-in-cheek assertion, Cafu and Roberto Carlos were busy redefining the role of the full-back for Brazil during the 1990s, but Alexander-Arnold is quite possibly the closest England have come to producing a player of such a lethal combination of flair and force.

The trade-off with Trent

Liverpool are the Premier League’s runaway leaders, 16 points clear at the top, 38 games without defeat in the league. Their points tally of 61 from 21 matches represents the best start to a campaign of any team in the history of Europe’s top five leagues.

But for all of their attributes and the accolades, it is Alexander-Arnold who is the principal playmaker. Across Europe’s top five leagues this campaign, only Kevin De Bruyne (14), Thomas Muller (Bayern Munich, 11), Luis Alberto (Lazio, 11) and Jadon Sancho (Borussia Dortmund, 9) have provided more assists.

This weekend’s clash at Anfield presents a fascinating clash of styles.

Manchester United boast the third-best record against top half of the table given their set up to counter-attack, losing just two of their 10 games, winning four and drawing four.

Ole Gunnar Solskjaer’s side only had 32 per cent possession during the emergence of Max Aarons at Norwich adding greater strength in depth to compete alongside the established pair of Kieran Trippier and Kyle Walker.

Where might Aaron Wan-Bissaka currently sit in the pecking order?

With Crystal Palace last term, his tackle count of 129 placed him third behind former Everton midfielder Idrissa Gueye (142) and Leicester’s Wilfred Ndidi (143) – earning him a £50m move to Manchester United last summer.

On Super Sunday, he will hope to further his claims to the position with the perfect opportunity to demonstrate his qualities when faced with nullifying Liverpool’s red arrows.

But, like Alexander-Arnold, he is not yet the finished article.

“What will define his Manchester United career, probably more than the defensive side, will be what he’s like in the attacking half of the pitch, where he probably hasn’t got as much experience,” Carragher said following United’s 1-1 draw with Wolves last August.

The expectation back then was that United would not struggle for clean sheets, but only Tottenham and Norwich (both two) have kept fewer than their four in the Premier League.

It would appear Wan-Bissaka loves nothing more than making tackles, but this is born out of necessity rather than preference. His explosive pace is often what gets him out of trouble to atone for his initial positioning.

Going the other way, Alexander-Arnold ranks first for assists and open play crosses since the start of last season, while Wan-Bissaka sits 82nd and 21st on the respective lists.

Where Klopp has all his pieces in place, this season has shown the jigsaw facing Solskjaer is a four or five-window project.

Where once the full-back was judged first and foremost on his ability to prevent wingers from gliding past them, mastering the art of one-on-one defending is no longer necessarily enough for international recognition.

Remarkably given his price tag, Wan-Bissaka is yet to earn a senior cap for England, and he remains eligible to play for the Democratic Republic of Congo.

Southgate has preferred to use full-backs capable of contributing offensively, and it may only be through United’s implementation of greater defensive insurance that Wan-Bissaka can fully fit his criteria, emulating Alexander-Arnold’s raids down the right channel.

Striking a balance between those natural defensive tendencies and having greater attacking output is his next challenge, and – by hook or by crook – it may just decide who wins the latest renewal of an old rivalry.
