Senne Lammens: Manchester United's Key Signing of the Season
Manchester United’s long search for certainty between the posts finally has a face. A 23-year-old Belgian who arrived almost unnoticed and has left the season with an award, a transformed defence and a transfer value that now belongs in elite company.
Senne Lammens has turned a problem position into a pillar of Manchester United’s 2025/26 revival.
From under-the-radar to signing of the season
United will remember this campaign as the year things started to make sense again, and the business done in 2025 sits at the heart of that shift. No deal has defined it more than the £18m move for Lammens.
He did not arrive with the fanfare of a marquee name. He arrived as a “data signing”, pushed by Tony Coton, and very nearly didn’t arrive at all. Ruben Amorim had set his sights on Emi Martinez. United went another way.
They gambled on the numbers. They backed their scouts. They ignored the urge to chase a World Cup winner and instead chose a young goalkeeper who barely registered outside specialist circles.
Ten months later, that call looks inspired.
Lammens walked into a club scarred by the failures of Andre Onana and Altay Bayindir. The position had become a running sore, a weekly debate, a source of anxiety. By week eight of the league season, he had the gloves and, crucially, never gave them back.
The impact was immediate. Command in the box. Clean handling. A calmness that spread through a previously jittery back line. Edwin van der Sar praised him. Peter Schmeichel added his voice. When United legends of that stature talk up a goalkeeper, people listen.
Supporters didn’t just listen; they voted. Lammens was named Signing of the Season by fans on TalkingPoints, recognition of a debut campaign that changed the feel of United’s entire defensive structure.
A £27.5m rise and a place among the elite
The numbers now tell the story as loudly as the performances. According to CIES, Lammens’ estimated transfer value has rocketed to £45.5m, a 150% rise from the £18m United paid last September. That’s a £27.5m increase in less than a year.
This isn’t just a tidy profit on paper. That valuation places him as the third most valuable goalkeeper in world football, behind only Gianluigi Donnarumma and Joan Garcia. From under-the-radar to standing in line with modern giants of the position in a single season.
What makes it more striking is that his year was not built on gaudy clean-sheet numbers. He took over in week eight and finished with eight shutouts. Respectable, not sensational. Yet the underlying work — the saves, the positioning, the authority — has driven his reputation and his value.
At 23, he is nowhere near his ceiling. That is what excites United most. If he can turn eight clean sheets into 15 next season, he will not just sit in the conversation with Donnarumma and Garcia; he will be breathing down their necks.
Chasing Raya and the Premier League benchmark
Globally, the valuation list does not include David Raya, largely down to the Arsenal goalkeeper’s age at 30. But in Premier League terms, Raya remains the benchmark Lammens must chase.
Raya’s 19 clean sheets last season bordered on outrageous. Arsenal’s controlled, cautious style helped him, but you still have to make the saves, still have to live with the pressure of a title chase. That’s the standard in front of Lammens now.
Right now, he sits in the “best of the rest” bracket, just outside the very top rung. He knows what it will take to climb. More consistency. More clean sheets. Fewer lapses on the ball.
His debut campaign brought 39 goals conceded, but the context matters. Many of those were unstoppable strikes, efforts no goalkeeper keeps out. By the club’s own assessment, only one goal could be pinned squarely on him: a poor pass against Liverpool that gifted the opposition.
What balanced that mistake was his work in preventing goals others would have let in. By goals-prevented metrics, Lammens ranked among the best in the league. Time and again he turned high-quality chances into mere near-misses, the kind of invisible work that doesn’t always make highlight reels but wins over analysts, coaches and, eventually, valuation models.
If he keeps that level next season, the numbers will fall his way. Fewer “worldies” will fly past him; the law of averages will finally do him a favour.
United’s new cornerstone
For United, this is about more than a clever piece of business. After years of turbulence in goal, they have a cornerstone again. A goalkeeper who looks like he belongs at Old Trafford, who carries the weight of the shirt without flinching, whose value off the pitch now mirrors his importance on it.
The club paid £18m for stability and upside. They’ve ended the season with a signing of the season, a £45.5m asset, and a 23-year-old who already sits in world football’s top tier of goalkeeper valuations.
The question now is simple: with a full campaign as undisputed No. 1 ahead of him, how far can Senne Lammens push himself — and how far can he drag Manchester United with him?
