Vinicius Junior enjoyed a winning debut for Real Madrid Castilla as he played 74 minutes of Sunday's win over Las Palmas Atletico.
The Brazilian teenager joined Los Blancos in a £40m transfer earlier this summer and has spent time training with the senior team.
After remaining on the bench for the UEFA Super Cup loss to Atletico Madrid and the La Liga win against Getafe, the 18-year-old was given minutes for Madrid's second-string side at the weekend.
Vinicius did not get on the scoresheet, but he was heavily involved in Castilla's 2-0 triumph.
Speaking on Saturday, Madrid boss Julen Lopetegui confirmed that Vinicius is part of his first-team plans for this season.
