Carlo Ancelotti says Vinicius Junior deserves patience and remains capable of influencing matches despite a difficult start to the season for Real Madrid.
The Brazil forward has scored only once in eight appearances in all competitions for Real Madrid, who are fourth in LaLiga with 15 points.
Vinicius Junior offered a reminder of his ability during Brazil's 4-2 friendly victory over Australia in Brisbane on Tuesday. The 26-year-old helped create Brazil's third goal before scoring their fourth from the penalty spot.
Ancelotti, who previously coached Vinicius Junior during his time in charge of Real Madrid, said the forward continued to have an important role for both club and country.
"I know Vini very well. To me, he is a key player for the national team - a key player for Brazil - and he was a key player in my own footballing journey," said Ancelotti.
"He is a key player for the future. Is he at his best right now? No, he isn't, but it is the start of the season. And Vini, always, even when he isn't at his best, he can still make the difference, just as he did today.
"The goal that really opened up the game was thanks to him. So, I'm going to be very patient, because he deserves that patience."
Ancelotti said Vinicius Junior had shown how he could contribute even when his performance was below its highest level, highlighting the role he played in breaking Australia's resistance.
Brazil's next fixture is another friendly, against India in Kolkata on Saturday.
