Middlesbrough FC have officially unveiled their new 25-26 third shirt, made by Castore. The design draws inspiration from one of the town’s most historic landmarks, the Masham Hotel, a Grade II listed building that once played a central role in the club’s early years as a gathering place for supporters.
