Gary Neville has publicly urged Manchester United to shore up their defensive frailties by acquiring at least one centre‑back and a full‑back before the transfer window shuts on Tuesday night. In recent weeks United have splashed a hefty £155 million on midfield reinforcements – Carlos Baleba, Andrey Santos and Youri Tielemans – and have also bolstered their attacking line‑up with signings such as Matheus Cunha, Bryan Mbeumo and Benjamin Šeško during the summer of 2025.

While those purchases have added quality in the middle of the park and further up the pitch, Neville argues that the back line remains a glaring weakness that could sabotage the progress made elsewhere. Speaking to Sky Sports ahead of United’s clash with Ipswich, the former England right‑back said, “If you asked Michael Carrick what he would have done this summer in a perfect world, he would probably say ‘rebuild the midfield and rebuild the defence.’” He went on to acknowledge the club’s measured approach, noting that United have already invested roughly £170 million in attackers last season and about £150 million in midfield this year, suggesting that the board are choosing to upgrade the squad piecemeal rather than launch a wholesale overhaul.

Neville stressed that United do have a handful of individually capable defenders, but they lack a cohesive back four. “When the team comes under sustained pressure, or when injuries start to pile up, that makeshift defence will crumble,” he warned.

“Michael knows that right now.” He added that securing a centre‑back and a full‑back before the deadline would at least mitigate the problems that are already evident in Premier League and Champions League fixtures. The former Manchester United captain expressed surprise that United have not added any defensive signings, especially when rivals such as Liverpool have already moved for two full‑backs. “Arsenal are strengthening while they sit at the top of the table. United and Liverpool are not in that position, yet their transfer activity on the defensive side has been almost non‑existent,” Neville observed.

On his own podcast, Neville elaborated on why the midfield must protect the back line. He highlighted Baleba as the most physical and defensively‑oriented midfielder, noting that his presence is crucial because United’s back four is vulnerable. “We conceded 50 goals last season with essentially the same defenders.

Unless the midfield shields them better, the goals will keep coming,” he said. Neville pointed out that United have already allowed four goals in just two league games this season and created numerous chances against Ipswich in the first half. He warned that without a defensive overhaul, United are unlikely to finish in the top half of the table.

“I’m not shouting ‘spend all your money,’ but the club rebuilt the attack last season and the midfield this season. It feels like the defence will wait another twelve months,” he argued. He speculated on potential targets, mentioning that while Lewis Hall of Newcastle appears to be an outstanding left‑back, the Magpies have made it clear he is not for sale. Similarly, Ian Maatsen of Aston Villa has been approached, but Villa intend to offer him a new contract.

Neville also named younger options such as Myles Lewis‑Skelly, who could operate as a left‑back or midfielder, but admitted that finding a quality defender on short notice is a challenge. Neville criticised United’s makeshift solutions in the recent Ipswich game, where Diogo Dalot and Luke Shaw were replaced by Leny Yoro at right‑back and Noussair Mazraoui at left‑back.

“Yoro is a makeshift full‑back at best, and Mazraoui, while capable, is not the natural left‑back United need,” he said. Looking ahead, Neville asked whether Carrick could allocate some of the remaining budget to bring in a defender now and perhaps spend less next season.

He suggested that even one or two signings could dramatically change United’s defensive dynamics. “If they can’t bring anyone in the next 48 hours, they will have to rethink the team structure,” he warned. Neville also hinted at tactical adjustments, such as becoming more compact and possibly altering the shape of the forward line, but stressed that these are stop‑gap measures.

The real solution, he believes, lies in adding genuine defensive talent. “When United face Everton next and then Manchester City in two weeks, they must be tighter and more compact defensively,” he concluded. In summary, Gary Neville’s message is clear: Manchester United have invested heavily in midfield and attack, but the defensive department remains under‑invested. With the transfer window closing imminently, United must act swiftly to secure a centre‑back and a full‑back, or risk a season plagued by leaky performances at the back.

The club’s current options are limited, but Neville insists that even a single quality signing could reshape the trajectory of United’s campaign.
