Adnan Januzaj says he doesn't "have any time to waste" in order to prove he is a good enough player for Jose Mourinho and Manchester United.
The 21-year-old joined the Red Devils as a wide-eyed 16-year-old from Anderlecht in 2011 and made huge strides in the club's reserve team, earning a call-up to the senior side under Sir Alex Ferguson at the end of the 2012/13 Premier League season – although he ultimately only made his debut under David Moyes.
He performed well in his first season and was even handed Ryan Giggs' number 11 jersey for the 2014/15 campaign, but a combination of poor form and reduced game time saw him loaned out to Borussia Dortmund one a season-long loan deal in 2015.
He returned to Manchester with only 12 games and three starts in the Bundesliga before joining Sunderland on a similar deal where he has impressed during a difficult time for the Wearside club.
Speaking to Belgian newspaper HLN Sport, Januzaj, who is currently nursing an ankle injury, said: "I understand that I was no priority for Mourinho.
"I don’t have to talk, I have to perform.
"I don’t have any time to waste I have to prove again that I am a worthy Manchester United player."
Januzaj’s father, Abedin, added that he makes sure his son behaves in the way he feels is correct for a professional sportsman: "I help Adnan in his sporting choices, and I make sure he lives as he should.
"As long as I can see it, you will see no piercings or tattoos on my son, no crazy hairstyles. He’s never drank a drop of alcohol, and in the evening he stays inside."
