Real Madrid has launched a home/away goalie jersey for the matches in La Liga and a third goalie jersey for the matches in UCL. Maybe there will be yet another goalie jersey released after Xmas in the new year 2025.
A fairly simplistic template with old school 1970s style adidas Trefoil logo.
The name and number kit suitable for the jersey is the same as for the outfield third jersey. Black with white logo in the number.
Here an example of a custom jersey using the official font. The reference is of course Iker Casillas. During his career Iker had a number of different variations of his name spelled out on the back. CASILLAS, I. CASILLAS, IKER CASILLAS, but as far as I know never simply IKER. Though IKER is common first name well when it comes to a footballing context and in particular in reference to a goal-keeper, well then it usually means just one thing. The IKER, as in Iker Casillas.
