The Brazilian has never scored against Jan Oblak.

Vinicius Junior is having a nice time at Real Madrid, scoring the goals and making wonderful assists.
Unfortunately, the Brazilian has never scored in a Madrid derby. Having played eight matches, he has been unable to find a way past Jan Oblak.
Even as he hasn’t scored against Atletico Madrid, his presence in itself is a good omen for Los Blancos. Against Atletico Madrid, Vinicius has been involved in four wins and four draws.
The only defeat he has experienced, he wasn’t on the pitch for, when Atleti overcame Real Madrid in the Supercopa de Espana in 2018.
