Trent Alexander-Arnold shirt number revealed ahead of Club World Cup debut

Trent Alexander-Arnold shirt number has been officially confirmed as No.12 by Real Madrid, ending speculation about what the England international would wear after his high-profile move from Liverpool. The club is set to unveil him ahead of the FIFA Club World Cup, where the right-back is expected to make his debut after a £10 million fee was paid to fast-track his arrival.
- Trent Alexander-Arnold will wear No.12 at Real Madrid
- La Liga rules prohibit shirt numbers above 25 for outfield players
- The defender chose “Trent” as his shirt name
- His debut could come in the FIFA Club World Cup
La Liga regulations prohibit first-team players from wearing numbers higher than 25, except for goalkeepers who typically use 13 or 25. As a result, Alexander-Arnold could not retain his iconic No.66 from Liverpool, a number he wore throughout his career at Anfield. Instead, he opted for No.12—most famously worn at the Bernabéu by Brazilian legend Marcelo, who spent over a decade in Madrid with that number.
The switch also comes with a change in the name on the back of his shirt. Rather than “Alexander-Arnold,” the 26-year-old defender will go by simply “Trent” at Real Madrid. He’s already updated his social media to reflect the rebrand, signaling a fresh start in Spanish football. His Instagram handle no longer includes the number 66, now streamlined to just @trent.
While some Liverpool fans reacted with frustration to the timing of his departure, the reception during his farewell appearance was overwhelmingly positive. Alexander-Arnold later acknowledged the emotional moment, saying, “To get the reception that I got means more than anything to me.” The six-year deal in Madrid suggests that both the player and the club view this as a long-term project.
As fans and pundits await his first appearance in white, attention will now turn to how Trent adapts to La Liga and life at one of the biggest clubs in the world. For those making LaLiga Predictions, the addition of a proven Premier League talent could shift Real Madrid’s dynamics on both flanks. His choice of No.12 not only respects the league’s traditions but also pays tribute to a club legend. It’s the beginning of a new story and the LaLiga Predictions landscape might be shifting already.
