Trent Alexander-Arnold has worn the No.66 shirt throughout his career at Liverpool but he will not be able to wear that number if he joins Real Madrid this summer

For instance, Raúl Asensio, a young talent at Real Madrid, was granted an exception to wear the number 35 jersey, as he was not subject to standard registration like senior players. However, for established players like Arnold, the implications are clear: his cherished number 66 will not be permitted if he makes the transfer to Madrid.

It looks like Trent Alexander-Arnold is closing in on his dream move to Real Madrid, crushing Liverpool fans' hopes of another Steven Gerrard-styled one-club hero. Such a quality player opens up an interesting new dynamic for the Spanish champions,
