The detail of the planned tribute matters.
Football tributes are often at their most powerful when they are understated. A pause in the game, a stadium joining together, and a visible show of respect from the players can say enough.
Castro joined West Brom as a teenager in 2021, and that matters in the way supporters will remember him. He was not just a name on an old team sheet; he was a young player who reached the first team.
That path is familiar in modern football: a young player fighting for minutes, moving through loans, chasing a foothold in the senior game.
After leaving Albion, Castro reportedly continued that search across several clubs in England before returning to his native Portugal and joining Real Sport Clube. That journey underlines the reality for many young professionals: careers can be nomadic, but the connections they make at formative clubs often last.
When West Brom face Burnley, the result will eventually matter again. Before that, the main focus will be remembrance - and a stadium acknowledging one of its former players at a moment far bigger than football.
