Manchester United's Left-Back Crisis: The £37m Gamble with Harry Amass
Manchester United’s summer rebuild is barely underway and already an old nightmare is back at the door.
Two years ago, they waved Alvaro Carreras off to Benfica for around £5.2million, a tidy sum for a young left-back who had barely scratched the surface of first-team football. Twelve months later, they watched him walk into the Bernabeu in a £42m deal to Real Madrid. A bargain for the Spaniards. A bruise for United.
Now Harry Amass sits in the same firing line.
The 19-year-old left-back, one of the most highly regarded prospects in the system, is being spoken about in the same breath as “auction” and “£6m”. Championship clubs are circling, Premier League scouts are paying attention, and United – again – are listening.
All this while Old Trafford is short of left-backs and long on regret.
Luke Shaw, 31, is entering the final year of his contract. The position has been patched up and shuffled around for too long, with injuries and makeshift solutions chipping away at any sense of continuity. Yet the club appear ready to cash in on Amass just as he reaches the stage where a pathway into the senior side should be opening up, not closing.
He has already had a taste. Seven senior appearances under Ruben Amorim before a Championship loan last season gave him the kind of grounding United usually insist their youngsters earn before any serious decisions are made. Now the decision could be to move him on permanently – for a fee that barely dents a modern transfer budget.
Supporters have not taken it quietly. Many have questioned how a club desperate for a long-term answer at left-back can justify letting one of their best young options leave for what they see as small change. The Carreras episode hangs over every conversation: another left-back, another cut-price exit, another potential fortune made elsewhere.
The worry is not just financial. It is philosophical. Under Michael Carrick, United are trying to rebuild a squad that can compete for major honours again, with academy talent threaded through the core. Letting Amass go, at a time when the club is loudly preaching youth and long-term planning, feels to many like a jarring contradiction.
Carrick’s first full season in charge starts away at newly-promoted Hull on August 22, and the defensive jigsaw is already complicated. Lisandro Martinez, injured in Argentina’s World Cup final defeat to Spain, has at least delivered a rare dose of good news. Tests revealed only a muscle strain and the centre-back is expected to be fit in time for the trip to the MKM Stadium, a huge relief after initial fears of a longer lay-off.
Even so, United’s likely back line for the opener underlines how tight the margins are. Heaven and Harry Maguire look set to continue as the central pairing, with new signing Matthijs de Ligt not due back until the autumn and Martinez only just returning. Shaw’s contract situation lingers in the background, and the club are still trying to decide which of their young full-backs to keep close and which to send out on loan.
Youth on the brink
The broader strategy around the academy is clear enough: almost the entire Under-21 squad has been put up for loan this summer. The club want real minutes for their prospects in the 2026/27 season, not just under-21 cameos.
Pre-season outings against Rosenborg and Wrexham have already showcased several of them. Shea Lacey, Ethan Williams and others have been handed meaningful game time, with the club using these fixtures as live auditions.
Yet even in this wave of outward movement, four names have been ring-fenced. Lacey, Jack and Tyler Fletcher, and JJ Gabriel are considered untouchable and will stay at Carrington. They are seen as central to the next phase of United’s homegrown core.
On the fringes of that group, Jaydan Kamason is forcing his own conversation. The 19-year-old full-back, the first player to sign a scholarship after coming through United’s Emerging Talent Programme, endured two long injury spells last season. Now he is making up for lost time.
Used in the early pre-season games against Wrexham and Rosenborg, Kamason exploded into life in Norway, stepping on at half-time for Maguire and delivering two superb assists. For a defender still establishing his name outside academy circles, it was a statement.
He knows what is at stake. Kamason has spoken openly about his ambition to break into Carrick’s plans this season, even if it means taking a loan first to bridge the gap. For him, “top level” means Manchester United, not just a professional career somewhere in the pyramid. Performances like Rosenborg suggest he is not content to be a footnote in the club’s loan army.
Carrick’s puzzle and the summer ahead
The rest of the pitch is hardly straightforward. In midfield, Kobbie Mainoo is nursing a back injury, while up front Benjamin Sesko is only just edging back from a shin problem. The Slovenia striker has missed the first two pre-season friendlies against Wrexham and Rosenborg, but his recovery is said to be on schedule.
Sesko has already started outdoor training and could feature against Atletico Madrid in Stockholm on August 1, with a stronger expectation that he will start against Paris Saint-Germain in Gothenburg a week later. United’s pre-season calendar – Atletico, PSG, Leeds, Milan – offers a steep gradient of tests as Carrick tries to refine his options.
For the opener at Hull, he may be forced into a slightly improvised attacking setup. With Sesko still building fitness, Bryan Mbeumo could be asked to lead the line, with Amad operating from the right and Cunha from the left. In midfield, Mason Mount may partner new signing Youri Tielemans, a pairing that offers control and guile but also demands protection behind them.
All of this unfolds against the backdrop of a striker market that refuses to sit still. Joshua Zirkzee, currently on United’s books, is a top target for Juventus, who are pushing to take him on loan with a £30m option to buy. Reports in Italy now suggest Juve are close to landing Randal Kolo Muani from PSG on a loan with a conditional obligation to buy, a move that could reshape the market and make Zirkzee’s long-term future even more uncertain.
United, for their part, have considered a move for former Juventus forward Dusan Vlahovic, now a free agent. The club’s stance is straightforward: if Zirkzee does head to Italy, an experienced striker must come in. Vlahovic, still in his prime years, fits that profile, but the economics and competition for his signature will dictate whether interest turns into action.
In midfield, the club are also pushing to add steel and intelligence. French World Cup winner Manu Kone has reportedly agreed personal terms and is eager to join Carrick’s side from Roma. United are said to be preparing a £42.7m bid, with discussions ongoing with the Italian club.
Falcao’s second act and the wider picture
Away from Old Trafford, a former United forward is preparing for a very different kind of comeback. Radamel Falcao, whose Premier League spells at United and Chelsea were costly and deeply underwhelming, is poised to step into international coaching.
Now 40 and a free agent after leaving Bogota club Millonarios, Colombia’s record scorer with 36 goals in 104 caps has been targeted by the FCF to become assistant to national coach Nestor Lorenzo. The move would give Falcao a chance to rebuild his reputation in a domain where his standing has never really dimmed: the Colombian national team.
A source close to Lorenzo told El Tiempo that the coach is open to Falcao joining his staff if he chooses to retire, stressing that it was the federation, not Lorenzo, who first put his name forward. For a player whose European legacy never matched his devastating spells at Porto, Atletico Madrid and Monaco, it could be a fitting next chapter.
Back in England, Gary Neville has been casting his eye over another of his former clubs – and this time it is Chelsea earning his praise. The London side have agreed a deal to bring in 35-year-old Danny Welbeck from Brighton on a two-year contract, and Neville believes the veteran striker, alongside Jordan Henderson, offers exactly what Chelsea have lacked.
He highlighted the absence of leadership and experience in a young, volatile dressing room and argued that Welbeck and Henderson, both Premier League title winners, will act as “guardians” of standards as much as contributors on the pitch. Between them, he believes they can still deliver 25–35 games a season while setting the daily example Chelsea’s youngsters have been missing.
Security, scrutiny and a season taking shape
Lisandro Martinez’s World Cup journey did not end the way he imagined. Forced off injured in the first half of Argentina’s final defeat to Spain, he could only watch as his side fell 1-0 after extra time. The aftermath back in England carried its own tension.
Both Martinez and Liverpool midfielder Alexis Mac Allister had private security stationed at their homes in the north-west in the days after Argentina’s semi-final win over England, when emotions were still running high. The image of Martinez clutching a banner reading “The Falklands are Argentina’s” during celebrations, with Mac Allister nearby, had stirred anger in some quarters.
No attempts were made to vandalise either property, and United were not involved in arranging the security detail for Martinez’s house. The episode passed without incident, but it underlined how quickly football, politics and raw national feeling can collide.
For United, the focus now is narrower and more immediate. Pre-season continues with Atletico Madrid in Solna, then PSG, Leeds and Milan. All four games will be available on MUTV, with the Atletico clash in Stockholm – 2pm UK time on August 1 – billed as the first serious examination of Carrick’s reshaped side against top European opposition.
By then, some of the summer’s big questions may already have answers. Will Zirkzee still be a United player? Will Kone be on the plane? Will Sesko be leading the line?
And, perhaps most tellingly of all, will Harry Amass still be wearing a United badge – or will the club have chosen to cash out on another young left-back, trusting that this time the story will not come back to haunt them?
