Bendtner joined the Black Cats on a season-long loan, close to the 11pm transfer deadline.
Sunderland boss Steve Bruce told his club’s official website: “I’ve had the privilege of working with Nicklas previously. I had him as an 18-year-old and he helped clinch promotion for Birmingham.
“He’s an outstanding talent and is a big, physical presence who will lead the line magnificently for us.”
