Trent Alexander-Arnold, 26, is a Real Madrid player from the 2025-26 season. The English right back strengthens a position that has caused a headache for the club since the injury of Dani Carvajal in October. The absence of the Spaniard has forced Carlo Ancelotti to rotate improvised options during the campaign, with Fede Valverde and Lucas Vázquez coming in several times.
The LaLiga Act prevents Trent's 66
The arrival of Alexander-Arnold will finally enable Madrid to double right back, allowing the manager to be alternated between Carvajal and the incoming Liverpool star. However, he will not be able to keep wearing the shirt number he has had since he broken in Liverpool: no. 66.
According to the Spanish League rules, only players registered with the first team can wear numbers 1 to 25, with 1 and 13 reserved for keepers (no. 23 usually goes to a third keeper), as explained in Article 239 about 'player uniforms'. That regulation makes Alexander-Arnold's Cherished No 66 offlimits in Madrid.
Why did Alexander-Arnold 66 chose?
He initially did not opt ​​for the number 66 for some sentimental reason. Such as Lee Radcliffe, the main kit manager of Liverpool, once explained on the club's website: “When we sign a young player who comes from the academy, we always deliberately give them a high number so that they can earn a lower one through their work and trouble and can feel more appreciated. But he really fell on 66 and never asked to change 66.”
Now he needs a new number. During his career he worn others – the No. 2 (currently Carvajal's), 15 (Arda Güler), 17 (Lucas Vázquez) and 18 (Jesús Vallejo). The last two are available, together with the departing Luka Modric's no. 10 – who is said to be handed over to Kylian Mbappé, because it is the number he is wearing for France. Alexander-Arnold can choose one of the available options or wait to see if more team changes open extra options.
One thing is certain … it's good to Trent 66.
