It is a weird thing to get attached to a number. Especially one that sounds like a highway or a route through the Midlands. But the Trent Alexander-Arnold jersey and that specific "66" on the back became a symbol of something bigger than just a kit. It was about a local lad who never felt the need to swap his humble beginnings for a "star" number.
He didn't want the number 2. He didn't want the number 7. He just wanted to play.
The Real Story Behind the 66
Most people think 66 was a calculated choice. It wasn't. Honestly, it was just the random shirt Lee Radcliffe, Liverpool’s kit management coordinator, pulled out of a bin when Trent first came up from the academy. The club has this policy: give the young kids high numbers so they don't get ahead of themselves. If you're wearing 66, you haven't "made it" yet.
But then he kept it. Through a Champions League trophy in Madrid and a Premier League title, the number stuck. It became a brand. Walk around Anfield today and you'll see more kids in 66 than almost any other number, maybe even beating out Salah's 11. It's the "homegrown hero" tax.

The Real Madrid Shift
Things got complicated in 2025. When the news broke that Trent was heading to the Bernabéu, jersey sales went into a frenzy. Collectors scrambled for the last Liverpool "66" kits, knowing a piece of history was closing.
But here’s the kicker about the Real Madrid jersey: La Liga is strict. You can't just pick any random high number like you can in the Premier League. First-team players in Spain generally have to stick between 1 and 25.
- The Number 12: Since 66 was against the rules, Trent took the number 12 in Madrid.
- The Legacy: He followed in the footsteps of Marcelo, another legendary attacking full-back.
- The Vibe: It feels different. Seeing "Alexander-Arnold" above a 12 instead of a 66 is like seeing a classic car with a new license plate. It's still him, but the aura has shifted.
Why Fans Still Buy the Liverpool Kit
Even with him playing in white now, the red Trent jersey hasn't lost its value. In fact, if you have an authentic 2019 or 2020 kit with the gold Premier League badges, you’re sitting on a goldmine. The 2024/25 "Last Dance" jersey—the one he wore before the move—is currently one of the most sought-after items on the secondary market.

People buy these because of the "corner taken quickly" against Barcelona. They buy them because of the 86 assists he racked up in a Red shirt.
Modern Tech: NFC Chips and Fakes
If you're looking to buy a Trent Alexander-Arnold jersey in 2026, you have to be careful. The new Adidas kits for Liverpool (yes, they switched back from Nike) and the Real Madrid kits are using advanced NFC chips.
- Authentication: You can literally tap your phone to the jersey to prove it's real.
- Digital Experience: Sometimes these chips give you access to exclusive content or "match-worn" digital certificates.
- The Fit: Be warned—the "Authentic" versions are incredibly tight. They are designed for athletes with zero body fat. If you're wearing it to the pub, just get the "Stadium" version. Your ribs will thank you.
What’s Happening Now?
Rumors are already swirling in early 2026 that Trent might be looking for a way back to England. Life in Madrid hasn't been a perfect fairy tale. If he does return, the question on every kit-man's mind is: does he go back to 66? Or has he outgrown the "scouser in our team" persona for something more traditional?

Actionable Advice for Collectors
If you want to invest in or wear a Trent kit, here is the move:

- Verify the Patch: A Champions League "15" patch on a Trent Madrid jersey is a massive flex right now.
The market for his gear is only going up. Whether he’s whipping crosses in at Anfield or the Bernabéu, the name on the back is what matters. The number just tells you which chapter of the story you're reading.
