The January signing from Leganes is beginning to prove his worth in front of goal for the Catalans. In ten appearances this season, Braithwaite has scored four goals - including three from three Champions League games.
And Junker is delighted for his countryman, telling Sport: "His latest performances have shown that he deserves to spend more time on the field. It is crazy to see him play for Barcelona because he is not the most gifted player, but we have great respect for his dedication and availability to work hard.
"He's fought to continue at Barça all season when it seemed he was on the verge of being transferred. I don't think Barcelona will sell him in January, even if it needs money."
And he has urged Braithwaite not to relax and make the most of the opportunity he's landed himself being on the books of Barca.
He added: “He must keep fighting on instinct.
"He knows that he is facing a unique opportunity to play for one of the biggest clubs in the world and that this opportunity will not be repeated."
Braithwaite, who also played in England with Middlesbrough, is contracted to Barca until 2024. He did feature in Saturday's disappointing 2-1 defeat to Cadiz, leaving Barca in ninth position on the LaLiga table with just 14 points from ten games.
