Full-Back Transfer Targets: Options for the Flanks

Let’s be honest: if you’ve been following Manchester United’s transfer windows over the past five years, you’ve heard the same promises about fixing the full-back positions. The club has spent significant money on Aaron Wan-Bissaka, brought in Diogo Dalot, and tried Sergio Reguilón on loan. Yet here we are again, with the same structural issues on the flanks. The problem isn’t just individual quality—it’s that United’s system under Erik ten Hag demands full-backs who can invert, overlap, and defend transitions simultaneously. Most players can do one or two of those things. Few can do all three.

Before we dive into names, let’s establish what United actually needs. The left side is the more urgent concern. Luke Shaw’s injury record has been a recurring issue. Tyrell Malacia hasn’t played a competitive match in an extended period. The right side is slightly less desperate—Dalot has shown improvement—but Wan-Bissaka’s contract situation and stylistic limitations make a long-term solution necessary. This article isn’t about predicting who United will sign. It’s about evaluating who they should be looking at, based on tactical fit, availability, and financial realism.

The Tactical Requirements: What Ten Hag’s System Actually Demands

If you watch United’s build-up play, you’ll notice something peculiar. When the team has possession, one full-back typically inverts into midfield while the other provides width. This isn’t revolutionary—Pep Guardiola has been doing it for years—but United’s execution has been inconsistent. The inverted full-back needs to be comfortable receiving the ball in tight spaces, making quick decisions under pressure, and covering ground when the opposition transitions.

The wide full-back, by contrast, needs pace, crossing ability, and the stamina to sprint up and down the flank for 90 minutes. United’s current options struggle with both roles. Shaw is technically capable but unavailable too often. Dalot is versatile but not elite at either function. Wan-Bissaka is excellent defensively but a liability in possession. The ideal signing would be a player who can do both, but those players typically command high fees. If United can’t afford that, they need to prioritize one profile and build around it.

Left-Back Options: The Urgent Priority

Profile A: The Inverted Left-Back (Midfield Hybrid)

This player would tuck inside when United have possession, allowing a midfielder to push higher or creating a numerical advantage in the center. The key attributes are passing range, composure, and positional intelligence.

Potential Target: Alphonso Davies (Bayern Munich) Davies is the obvious dream signing, but let’s be realistic. His contract situation at Bayern is uncertain, which means the club could face a decision soon. The Canadian is one of the few full-backs who can genuinely play both roles—he has the pace to overlap and the technical ability to invert. The problem? Several top clubs are reportedly interested, and his wage demands would likely be high. United would need Champions League football and a massive salary package to compete. It’s not impossible, but it’s improbable.

More Realistic Option: Jérémie Frimpong (Bayer Leverkusen) Frimpong is technically a right-back, but he’s played on the left for Leverkusen under Xabi Alonso. His attacking output is elite—he contributed to a significant number of goals last season. The concern is defensive discipline. He’s a wing-back in a back-three system, not a traditional full-back. United would need to adjust their defensive structure to accommodate him. That’s not necessarily a dealbreaker, but it’s a risk.

Profile B: The Traditional Left-Back (Defensive Stability)

If United prioritizes defensive solidity first, they’ll look for a player who can hold the line, track runners, and provide occasional attacking support.

Potential Target: Milos Kerkez (Bournemouth) The Hungarian international has been impressive in the Premier League, showing composure beyond his 20 years. He’s not flashy, but he’s reliable. His passing accuracy is solid, and he makes intelligent runs into half-spaces. The question is whether he can handle the step up to a club that expects to dominate possession. At Bournemouth, he’s often defending deep. At United, he’d need to attack more frequently.

Sceptical Take: Kieran Tierney (Arsenal) Tierney is available, experienced, and knows the Premier League. He’s also had a lengthy injury history. Since joining Arsenal in 2019, he’s missed substantial playing time through injury. If United is tired of Shaw’s absence, signing Tierney is like swapping one injury-prone left-back for another. The only argument in his favor is cost—he’d likely be available for a relatively modest fee. But cheap doesn’t mean good value if he’s not on the pitch.

Right-Back Options: Planning for the Future

Profile A: The Modern Full-Back (Attack-First)

United’s right side has been less problematic than the left, but that’s partly because the club has invested more resources there. Dalot is a solid squad option, but he’s not a game-changer. The ideal right-back would combine Dalot’s technical ability with Wan-Bissaka’s defensive instincts.

Potential Target: João Cancelo (Manchester City) Cancelo is the definition of a modern full-back—he can invert, overlap, and even play in midfield. But there are red flags everywhere. His time at City ended under difficult circumstances, he had a loan spell at Bayern, and is now at Barcelona. He’s also 30 years old. United would be buying a short-term solution with long-term baggage. The talent is undeniable, but the fit is uncertain.

More Sustainable Option: Malick Yalcouyé (IFK Göteborg) This is a speculative pick, but one worth monitoring. Yalcouyé is an 18-year-old Malian who has been turning heads in Sweden. He’s raw—his positioning is inconsistent, and he can be caught out defensively—but his physical attributes are exceptional. He’s tall, rapid, and comfortable on both feet. United would need to loan him out for a season or two, but the long-term potential is there.

Profile B: The Defensive Specialist (Complementary Option)

If United signs an attacking left-back, they might prefer a more conservative right-back to balance the defense.

Potential Target: Noussair Mazraoui (Bayern Munich) Mazraoui is technically gifted and tactically flexible. He can play either full-back position and has experience in Ten Hag’s system from their Ajax days. The issue is his injury history—he’s missed time at Bayern with various issues. When fit, he’s a reliable performer. But “when fit” is doing a lot of work in that sentence.

Sceptical Take: Emerson Royal (Tottenham) Emerson is a hard worker and a decent defender, but he’s limited in attack. His crossing is below Premier League standard, and he struggles against teams that sit deep. United would be buying a player who solves one problem (defensive stability) while creating another (lack of attacking threat). That’s not progress.

The Financial Reality: What United Can Actually Afford

Let’s talk about the elephant in the room: Financial Fair Play. United has spent heavily in recent windows, and the club’s debt remains substantial. The Glazers’ ownership situation adds another layer of uncertainty. Even with new minority investment from Sir Jim Ratcliffe, United won’t have unlimited funds.

The sensible approach would be to target one premium signing and one budget option. That would represent a significant total investment, which is feasible if United sells players like Wan-Bissaka, Donny van de Beek, and Harry Maguire.

The Verdict: What Should United Do?

If I were in charge of recruitment, I’d prioritize the left-back position first. Signing Alphonso Davies would be transformative, but the odds are against it. A more realistic plan would be to pursue Jérémie Frimpong and use the savings to reinforce other areas. Frimpong’s defensive limitations can be mitigated by a strong defensive midfielder and a disciplined center-back pairing.

On the right side, I’d sell Wan-Bissaka and promote a youth player as backup to Dalot. United has several promising full-backs in the academy, including Sam Murray and Harry Amass. Neither is ready for first-team football, but they could provide cover in cup competitions and lower-pressure matches.

The key is to stop treating full-backs as an afterthought. United has spent substantial money on defenders since 2019, yet the defense still looks disjointed. That’s not a scouting problem—it’s a planning problem. If the club can identify a clear profile, commit to a signing, and build the system around that player’s strengths, the full-back positions can become strengths rather than weaknesses.

The next transfer window won’t solve every problem, but if United gets the full-back positions right, the rest of the team will look significantly better. That’s not optimism—it’s basic squad construction.
