Futebol Clube do Porto "Juniors" (Portuguese: Juniores), commonly known as Porto Juniors, is the under-19 football team comprised in the youth department of Portuguese club FC Porto. Based in Olival and Crestuma, two local civil parishes part of the Vila Nova de Gaia municipality, they hold home matches at the club's training complex, CTFD PortoGaia. Domestically, Porto have won 23 Campeonato Nacional de Juniores titles. Internationally, they won the Blue Stars/FIFA Youth Cup in 2011 and the UEFA Youth League in 2019. In the latter, they became the first Portuguese club to conquer the competition and were also distinguished with the "UEFA's Best Educational Action" award. Between the department's several development teams, two other youth categories complete the three main age groups, the Juvenis (under-17) and the Iniciados (under-15), who compete in their respective national leagues organised by the Portuguese Football Federation.

Moreirense was founded in 1938. It first reached the second division in 1995, returning again six years later, and immediately promoting to the top flight, with manager Manuel Machado leading the northerners to two consecutive championships. From 2002–04, Moreirense achieved two mid-table positions in the top division, finishing a best-ever ninth in the latter season. As Machado departed for neighbouring Vitória de Guimarães, the club suffered two consecutive relegations, only returning again to the second level in 2010, and the first in 2012.
