Real Madrid attacker Vinicius Jr admits he's not been at his best for Brazil.

Vinicius concedes he wasn't good enough for defeat to Uruguay.

"I was very bad in the game, I was very bad in the last game too. I have a lot to improve, the team also has a lot to improve. But it's about having a clear head to be able to do the best for the team," said Vinicius Jr.

"I think that my cycle in the National Team has not yet been what I expected. I have a lot to improve to be able to play the best I can, as I do at Real. Of course, the pressure is also great.

"And I am always prepared. Wanting to evolve, wanting to improve as quickly as possible to be able to help the team."
