Manchester United boss Ruben Amorim has admitted that his squad lacks an attacking wing-back on the opposite flank — a role he believes is vital for his system’s success. Speaking ahead of his side’s upcoming match against Crystal Palace, Amorim said the club needs “another wing-back like Amad Diallo” to balance defence and attack under his preferred 3-4-2-1 formation.
Amorim’s candid admission follows his side’s disappointing 1-0 home loss to Everton. He reflected on the match, noting that when Everton were reduced to ten men, Manchester United lacked the offensive bite down the left because he replaced a natural wing-back with a conventional full-back. That change, he acknowledged, exposed the team’s limitations.

A midfield flip that cost United
In the buildup to Everton’s defeat, Amorim had opted for a formation that logically demanded two dynamic wing-backs capable of bombing forward — but the personnel did not match the tactical demand. The decision to field Diogo Dalot on the left instead of a more attack-minded player left United light on offensive threat when they desperately needed to press. Amorim himself said that what was needed “was an Amad with the right foot to put on the other side.”
The Diallo difference
Amad Diallo has often been the only outlet providing width and threat from the flanks this season. Under Amorim’s system, his ability to blend attacking flair with defensive work has stood out, and that, the manager insists, is the model for any new signing in the wing-back role.
Supporters of Amorim’s approach point out that the right kind of wing-back can transform the team’s play: someone with Diallo’s explosive pace, crossing ability, and stamina could make the difference between a wasted formation and one that dominates possession while creating real chances.
Why Manchester United must act this winter
With their current options failing to replicate Diallo’s impact, the January transfer window looms as a crucial moment for Manchester United. Signing a second attack-minded wing back could give Amorim’s 3-4-2-1 the balance it currently lacks, ensuring that when one flank overloads, the other can still deliver aggression and width.

For now, supporters and pundits will watch closely to see whether the club heeds Amorim’s call. If they do, United could find themselves better equipped to challenge the upper tiers of the Premier League.
