Michael Carrick's Boro rounded off the Portugal training camp with a 1-0 win against Europa League-bound Vitoria SC.
Marcus Forss scored the decisive goal in a behind-closed-doors friendly that saw Carrick utilise his squad to the full.
Alex Gilbert pulled on a Boro shirt for the first time along with Rav van den Berg and Sammy Silvera, who both came on for the final stages.
The game also marked a first outing for Boro's new 2023/24 home kit.
